Severe Plastic Deformation (SPD) has been explored in a wide range of metals and
alloys. However, there are only a few industrial scale implementations of SPD for commercial
alloys. To demonstrate and evolve technology for producing ultrafine grain metals by SPD, a
Nanostructured Metals Manufacturing Testbed (NMMT) has been established in Golden,
Colorado. Machines for research scale and pilot scale Equal Channel Angular Pressing-Conform(ECAP-C) technology have been configured in the NMMT to systematically evaluate and evolve SPD processing and advance the foundational science and technology for manufacturing.
We highlight the scientific and technological areas that are critical for scale up of continuous SPD
of aluminum, copper, magnesium, titanium, and iron-based alloys. Key areas that we will address in this presentation include the need for comprehensive analysis of starting microstructures, data on operating deformation mechanisms, high pressure thermodynamics and phase transformation kinetics, tribological behaviors, temperature dependence of lubricant properties, adaptation of tolerances and shear intensity to match viscoplastic behaviors, real-time process monitoring, and mechanics of billet/tooling interactions.
