摘要	The microstructure of Ti - 49.8 at.% Ni alloy, which was cold rolled to about 30% reduction in thickness in its martensitic condition and subsequently heated up to 200 degrees C for half an hour, has been studied by high resolution electron microscopy. The newly-formed parent phase has an orientation relationship with the residual martensite: [11(1) over bar](P)//[<1(1)over bar>0](M), (101)(P) 6.5 degrees away from (001)(M). The parent phase-martensite interface is not smooth and well coherent. The boundary between two subgrains of the parent phase is not straight and perfectly coherent, with partial dislocation observed at the interface. Inside some parent phase grains, thin plate-like {114} and spear-like {112} twin-related parent phase variant pairs are observed. The {114} twinning boundary is relatively straight, but with two or three atomic-height blurred layers existing near the interface. (C) 1999 Elsevier Science B.V. All rights reserved.
