【摘要】 通过对ＦｅＮｉＣ系合金母相的室温预变形处理，考察了不同母相预变形量对随后冷却的马氏体形态及亚结构、相交点Ｍｓ等的影响，说明母相的屈眼强度和结构状态是影响马氏体形态及其转化的重要因素，决定着马氏体相变形状应变的协调方式：母相塑性协调或马氏作变体间的自协调。更多还原

【Abstract】 Effect of different extent of parent phase pre forming of FeNiC series alloy on the form, substructure and phase-cange point Ms of martensite cooled after pre forming treat under atmospheric temperature isstudied. It is concluded that the yield strength and structure are the main factors to affect martensite3 they determine the harmonization mode of phasechange strain of martensite: plastic harmonization of parent -phase or selfharmonization between phase--change states of martensite.更多还原
