【摘要】 本文在14MnNi和12CrNi3两种低碳合金钢上研究了冷变形织构,高温形变淬火织构及其遗传现象,认为,α相的形变织构会通过快速加热和快速冷却的α-γ-α相变后遗传给α相。其遗传程度可用织构发展程度参数∑⊿Phkl定量地予以衡量。形变织构愈强烈,经急热急冷相变后遗传下来的织构亦较强烈。本文较详细地讨论了织构与韧性的关系,并认为(111)织构的韧化作用已被较多的试验所证实,但韧化机制尚很不清楚。更多还原

【Abstract】 The cold, high temperature deformation textures and their inheritance were studied on two low carbon alloy steels 14MnNi and 12CrNi3.It was found that the texture of initially deformed-phase can be inherited after α→γ→α transformations.The degree of textural inheritance may be measured quantitatively by using the parameter of the growing level of texture ∑△P_hke.The stronger the deformation texture,the higher the degree of its inheritance after α→γ→α transformations with rapid heating and rapid cooling. The relationship between toughness and texture was discussed in detail and it is believed that the（111）texture is apparently benifcial to the increase of toughness of cold and hot deformed steels.更多还原
