摘要：
Martensitic transformation was investigated in an aged NiTi alloy with DSC and a temperature controllable TEM specimen stage to observe the influence of T11Ni14 precipitates and R-phase on martensitic transformation in situ. The R-phase, conventional martensitic twins, and a new morphology of interwoven austenite/martensitic structure were observed. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd.
