| 摘要： | Major Goals: This proposal desires to acquire a nano-mechanical testing equipment for measurements of compressive and tribological properties on superior performance nanostructured metal based materials fabricated by laser deposition-additive manufacturing (LD-AM) for both research and education purposes. The objectives of this acquisition are: To generate new enablers for superior performance nanostructured metal based material developing and high ends defense device manufacturing, which are desired by AFOSR, ARO, and ONR; To develop processing-property-performance relationships by integrating the requested equipment with existed equipment; To enhance the capabilities for fabrication and remanufacturing of difficult-to-machine and high failure resistance parts by LD-AM; and To support and improve DoD desired university STEM education for future U.S. domestic workforce in the areas of advanced manufacturing and material science. Many DoD interested superior failure-resistant materials (bulk parts and coatings) have been fabricated by the LDAM process. These materials include nanostructured super alloys, nanoparticle or nano-precipitate reinforced metal matrix composites, and high indentation and creep resistance thin film materials. The requested equipment will be a key instrumentation for fabricated parts testing and evaluation. The obtained nanoscale mechanical properties can provide better understandings of LD-AM processing mechanism which will benefit the current defense industry desired materials fabrication, special military applicable structure deposition, and new materials development. The requested equipment will promote current LD-AM researches and enable new research areas. |
