镍钛合金中富钛相的沉淀与相变

PRECIPITATION OF TI-RICH PHSAE AND PHASE TRANSITION IN NITI ALLOY

本文报道了在含富钛的镍钛合金中,由于时效引起的富钛相沉淀及其对马氏体相变内耗、模量、电阻等性能的影响.讨论了在二元系合金中由于沉淀相而出现无公度相的可能性。

Ti-rich Precipitation phsae in Ti-rich NiTi alloy after ageing at 500℃ was Observed.The effects of Ti-rich Precipitation phase on the phase Transition and properties of alloy were discussed.Thereby the possibility of incommensurate Phase occurring in the binary alloy system was also studied.
