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。
In this paper, cold deformation texture, high temperature deformation quenching texture and its genetic phenomenon were studied on 14MnNi and 12CrNi3 low carbon alloy steels. It is considered that the deformation texture of α phase can be rapidly transformed by rapid heating and rapid cooling of α-γ-α After the phase transition to alpha phase. The genetic extent can be quantified using the texture development parameter Σ⊿Phkl. Deformation of the texture of the more intense, rapid quench phase transformation inherited texture is also more intense. In this paper, the relationship between texture and toughness is discussed in detail. The toughening effect of (111) texture has been confirmed by many experiments, but the mechanism of toughening is still unclear.
