Abstract:

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.
