摘要

摘要: 对冷轧低碳钢在高压下进行再结晶，用透射电子显微镜（TEM）分析高压相变组织，发现压力可以使再结晶晶粒细化；压力升高，具有体心立方结构的普通低碳钢可形成-马氏体，并根据电子衍射花样的计算确定-马氏体的晶格参数。

Abstract: In this paper we investigate the recrystallization of being cold-rolled low carbon steel under high pressure and analyzes the structure of phase transition under high pressure by TEM technique. It was found that the high pressure can make the recrystallized grains ultrafine; the structure of low carbon steel can change from the body-centred cubic (BCC) to -martensite (HCP) with the increase of high pressure. The lattice constant was calculated based on the electron diffraction pattern.
