Abstract

It this study was investigated the microstructure of Ti‐6Al‐4Nb and Ti‐10Al‐4Nb alloys processed using plane strain compression test (PSCT) in the β phase region (1050°C). PSCT was performed with strain rate of 0.1 s‐1 to obtain about 70% of deformation. High‐resolution EBSD was successfully used for precise phase and texture characterization of these alloys. The microstructure of homogenized samples was composed of mainly α phase and thin β phase plates between α phase grains. Dynamic recrystallization occurred partially in both alloys, but grains size after dynamic recrystallization in Ti‐10Al‐4Nb was smaller than that in Ti‐6Al‐4Nb due to smaller initial grain size.
