Synthesis and Characterization of an Ultrafine-Grained Aluminum-Copper System through High-Pressure Torsion

Creator:

Liang, Guangyuan

Abstract:

Aluminum and copper and their alloys have been widely used due to relatively high strength-to-weight ratios compared with conventional steels. Processing of these alloys is typically conducted at high temperatures over extended time periods. High-pressure torsion (HPT) is a promising processing technique for introducing significant grain refinement leading to excellent...

Synthesis of Heterostructured Aluminum-magnesium System with Extreme Specific Strength Through the Application of High-pressure Torsion

Creator:

Han, Jae-Kyung

Abstract:

Processing of metals through the application of high-pressure torsion (HPT) provides significant grain refinement in bulk metals at ambient temperatures. The ultrafine-grained (UFG) materials processed by HPT generally demonstrate the superior physical and mechanical characteristics. For utilizing the benefit of HPT, the feasibility of conventional HPT processing was demonstrated recently...
