    • Deformation Processing 

      FC Campbell (2013-12-03)
      Metalworking processes are commonly classified as either hot working or cold working operations. Primary metalworking processes, such as the bulk deformation processes used to conduct the initial breakdown of cast ingots, ...
    • The development of hardness homogeneity in aluminum and an aluminum alloy processed by ECAP 

      Cheng Xu; Terence G. Langdon (2013-12-03)
      Equal-channel angular pressing (ECAP) is an effective fabrication process for obtaining ultrafine-grained materials. This paper examines the development of homogeneity in materials processed by ECAP with emphasis on samples ...
    • Enhancement of strength and superplasticity in a 6061 Al alloy processed by equal-channel-angular-pressing
