Continuous Processing of Ultrafine Grained Materials by ECAP-Conform

Abstract
Invention describes a machine for producing continuous pieces of ultra-fine grained materials in bar or rod shape.  Ultra-fine grained materials have extremely high strength while maintaining significant ductility.  This machine can process almost any metal.  Preliminary data for aluminum show a yield strength of 20 ksi (140 MPa) (vs. 6.8 ksi for unprocessed material) with an elongation at failure of 12% (vs. 28% for unprocessed material).
