英文摘要	Multiple-stage transformation of Ti49.2Ni50.8 alloy processed by equal channel angular pressing (ECAP) was investigated as a function of pass number and aging treatment before ECAP. When the pass number is no more than four passes, three stage transformation, namely A -> R, R-1 -> M-1 and R-2 -> M-2, occurs in the as-ECAP processed alloy initially aged at 450 degrees C for 60 min. Only the A -> R -> M forward transformation occurs provided that the aging duration was decreased/increased to 10/600min. The transformation sequence was discussed based on the microstructure evolution of as-ECAP processed alloy with different initial microstructure and pass number. (C) 2017 Elsevier Ltd.
