Effect of grain size on deformation behavior of pure rhenium

A comprehensive study of grain size effect on twins, slips and work hardening of rhenium during tension was conducted using EBSD and SEM analysis. Slip/twinning trace and Schmid factor (SF) were analyzed to elucidate the activities of deformation modes. The deformation behavior was found to be sensitive to grain size. Non-basal slips and {112¯1} <1¯1¯26> extension twins were found to be the dominated deformation modes in the samples with large...
