A -- LONG RANGE SCIENTIFIC PROJECTS SOL BAA 02-95 DUE 113095 POC Mrs. Pat Schaefer, Code 3210, FAX (202) 767-6197, BBS (202) 404-8007 (select B from main command, then L, then topic number or 5a,5b,5c,5d, 5e, 5f, or RDSC), and internet http://www.nrl.navy.mil/BAA/baa.html. This amends the advertisement appearing in the CBD issue dated 01 December 1994 and BAA publication 02-95, date of issue 01 December 1994. Three additional topics, BAAs 570, 571, and 572, are hereby added as part of the publication, and complete descriptions of each additional topic listed in this addendum are provided below. There are and have been no changes to the ground rules, proposal instructions, award considerations or other non-topic text contained in BAA booklet 02-95 as originally issued; the only changes have been the addition of topics as described in Addenda 1 and 2. Requests for a printed copy of booklet BAA 02-95 MUST BE IN WRITING and transmitted by FAX or mailed to the number or address above. However, downloading from the electronic bulletin board (BBS) or World Wide Web (WWW) is strongly encouraged and will save several weeks processing/mailing time; the substantive content of the booklet as contained in the BBS and WWW is identical to the printed version, except that the BBS also contains a description of R&D Streamlined Contracting Procedures (not necessary for submitting BAA proposal). The following BAA topics are issued as Addendum #03 to BAA 02-95: BAA 570, SILICON-GERMANIUM MICROELECTRONICS TECHNOLOGY. The Naval Research Laboratory (NRL) is interested in receiving proposals which will advance the state-of-the-art of SiGe microelectronic device and circuit technology. The primary areas of interest include extending the state-of-the-art of SiGe heterojunction bipolar transistor (HBT) microelectronic circuits, and exploration of the potential of SiGe field effect transistor (FET) technology for digital logic. Proposals for the SiGe HBT circuit area should explore the limits of A/D, D/A, or frequency synthesizer circuits. Several circuit categories of interest include high dynamic range (16 bit), high conversion rate A/Ds for radar, high conversion rate A/Ds for electronic warfare, and high frequency (3 GHz) direct digital frequency synthesizers for communication. Cost sharing for the SiGe HBT circuit development area is desirable. Proposals for the SiGe FET area should be directed towards development of a technology suitable for digital logic. The proposal should discuss the expected performance advantage of the SiGe FET technology and areas where further development is needed to make the technology compatible with conventional BLSI processing. Characteristics desired for SiGe FET technology include the potential for increased performance, a large number of gates, low gate leakage, low off-state leakage, low power dissipation, good reliability, and good noise margin. For proposals for the SiGe FET development area, the proposer should have demonstrated state-of-the-art SiGe material growth capabilities and have experience in fabricating SiGe FET devices. Proposals should include the delivery to NRL of a sufficient number of devices to allow NRL to perform reliability and performance characterization. The foregoing description should be interpreted within the following guidelines which apply to all BAA topics but are stated here for emphasis: (1) NRL is not interested in concepts that already have been developed or proven (even if they never have been sold before); (2) NRL seeks proposals for scientific study and experimentation directed toward advancing the state-of-the-art or increasing knowledge or understanding; and (3) deliverables should demonstrate the results of scientific study and experimentation rather than focus on a specific system or hardware solution. It is anticipated that the award amount will be somewhat below the middle of the range specified in the preface. Performance over periods up to 24 months is anticipated. The government will take title to any test fixtures, wafers, chips, devices, circuits or any other experimental prototypes from this effort. It is preferred that the proposal be unclassified. Address Initial Proposals to Dr. Fritz Kub, Code 6813, (202) 767-3862. Allow one month before requesting confirmation of receipt of Initial Proposal, if confirmation is desired. Substantive contact should not take place prior to evaluation of an Initial Proposal by NRL. If necessary, NRL will initiate substantive contact. BAA 571, LOW COST, HIGH TEMPERATURE STRUCTURAL CERAMICS. Basic and applied research is needed in the area of processing and fabrication of high performance ceramics and ceramic matrix composite (CMC) materials for wear, chemical processing and high temperature structural applications. The most significant of the latter applications are in advanced gas turbine and ramjet engines with the former including both small gas turbines (APUs, cruise missile engines) and large gas turbines for DoD and commercial aircraft. The ceramic matrix composites of interest here nominally consist of a refractory ceramic matrix material, reinformed by refractory ceramic fibers, whiskers, and/or particles to achieve both higher toughness and higher design strengths. The ceramic matrix composites may be used by themselves or in conjunction with other materials, as in laminates, sandwich structures or other hybrid materials where these combinations improve performance. Ceramics of interest here include those with minimal variability in strength, insensitivity to pre-existing flaws and high damage tolerance. The particular areas of interest include: (1) Innovative techniques for the preparation of materials which have good structural and other properties, competitive with metallic materials at temperatures over 1000 degrees C. (''Structural properties'' here refer to strength/weight, stiffness/weight, thermomechanical fatigue resistance, and high temperature creep resistance; ''other properties'' include thermal expansion, thermal conductivity, and chemical, abrasion, and oxidation resistance.) (2) Innovative techniques for production of CMC materials, or monolithic ceramics strengthened or toughened with CMCs or by other techniques, to net shape or near net shape. (3)Innovative techniques for production of these composite materials at costs consonant with DoD and commercial applications and/or production of composites, ceramics or hybrids with lifecycle costs lower than currently used materials. (4) Innovative uses of novel material processing techniques and material combinations for lowering component cost and increasing structural efficiency. (5) Novel design algorithms, tools, codes and NDE/NDT techniques for selecting such materials and predicting their performance in service in particular applications. The foregoing description should be interpreted within the following guidelines which apply to all BAA topics but are stated here for emphasis: (1) NRL is not interested in concepts that already have been developed or proven (even if they never have been sold before); (2) NRL seeks proposals for scientific study and experimentation directed toward advancing the state-of-the-art or increasing knowledge or understanding; and (3) deliverables should demonstrate the results of scientific study and experimentation rather than focus on a specific system or hardware solution. Address Initial Proposals to Dr. David Lewis III, Code 6384, (202) 767-2131, FAX (202) 767-1349. Allow one month before requesting confirmation of receipt of Initial Proposal, if confirmation is desired. Substantive contact should not take place prior to evaluation of an Initial Proposal by NRL. If necessary, NRL will initiate substantive contact. BAA 572, MATERIALS PERFORMANCE, PROCESSING, AND MODELING. The Naval Research Laboratory is interested in receiving proposals for research and development in materials, their joining, and their processing, including modeling of materials performance and joining and forming processes to achieve cost-effectiveness. The areas of research and development activities of interest to NRL include, but are not limited to, the following: (1) Microstructural/continuum modeling for the development of predictive equations of state for materials which could greatly reduce costs of developing new alloys and forming processes as well as permit optimization of properties and plant utilization. This include primarily, but is not limited to, weldable aluminum and iron alloys of high strength, toughness, stress corrosion cracking resistance, reduced hydrogen embrittlement, etc. (2) Forming and machining of hard-to-form and/or-machine alloys by the application of high fields. This may include the application, singly or in combination, of electric, magnetic, ultrasonic, and microwave fields and address the casting and/or forming to near-net-shape by rolling, drawing, or forging and the machining by point cutting or grinding of any low ductility materials such as tungsten alloys, aluminides, etc. (3) Design of manufacturing processes that achieve desired product attributes at lowest total life cycle cost. This may include the integration of several unit forming processes and the simulation of such processes to account for geometric effects and the effects of evolving material microstructure and temperature and stress fields. Total life cycle spans issues from the initial material synthesis to the final disposition of components including all costs of acquisition and ownership. Address Initial Proposals to Dr. S. C. Sanday, Code 6303, (202) 767-2264. Allow one month before requesting confirmation of receipt of Initial Proposal, if confirmation is desired. Substantive contact should not take place prior to evaluation of an Initial Proposal by NRL. If necessary, NRL will initiate substantive contact. Proposals involving cooperative research arrangements are welcome. Academic institutions, small disadvantaged-businesses, historically black colleges and universities, and minority institutions are especially encouraged to participate. As noted above, the BAA is available on the Internet, specifically the World Wide Web via MOSAIC at the following address: http://www.nrl.navy.mil/BAA/baa.html. The number of the electronic bulletin board for downloading the BAA in whole or in part is (202) 404-8007. The board can transmit at rates up to 9,600 baud. It is available 24 hours per day. Support to users is not available, and callers assume risks of use. However, the board is configured for downloading only, incorporates anti-viral software, and is regularly maintained. It is suggested that institutions having an Office of Sponsored Research use the office as point of contact in writing requests. The announcement of topics 570, 571, and 572 will remain open until 30 November 1995. Proposals may be submitted anytime during this period; however they must be in accordance with the detailed publication. (0142)
