aluminum alloy induced by severe plastic deformation at room temperature [J]. Appl Phys Lett, 2007, 90(8): 083115-1-083115-3. [12] ZHILYAEV A P, LANGDON T G. Using high-pressure torsion for metal... to high pressure torsion. These observations are surprising because deformation twinnings have never been observed in their coarse-grained counterparts under normal conditions. Experimental evidences......
; Abstract: Tension attachment of high temperature microscopy was proposed to research the microstructure evolution and plastic behavior of AZ31 magnesium alloy... and grain boundaries, suggesting both twinning-induced DRX and continuous DRX occurs in the deformation process. Key words: magnesium alloy; twinning; high temperature microscopy; microstructure ......
in annealing temperature range of 150-300 ℃. Then the effects of the different annealed microstructures on high-temperature deformation behavior were further studied. The results indicate that the initial... D H. High strain rate superplasticity of submicrometer grained 5083 Al alloy containing scandium fabricated by severe plastic deformation [J].
