| 摘 要： | 仅含碳、硅、锰合金元素的结构钢，采用临界区等温淬火热处理工艺，得到铁素体、贝氏体和残余奥氏体三相组织。该钢在 Ｍｓ（马氏体转变开始温度）～Ｍｄ（马氏体转变终止温度）ｄ温度之间形变，应变诱导相变，相变诱发塑性──ＴＲＩＰ，其力学性能指标大大提高。本文通过显微组织观察，力学性能结果分析，对这种低碳硅锰系ＴＲＩＰ钢三种不同的热处理工艺制度进行了研究。

| Abstract: | Bainite, ferrite and retained austenite were obtained through austempering immedidely after critical annealing in the plain - carbon steel containing C. Si and Mn alloying elements.The mechanical properties of this sort of steel have been enhanced considerably due to strain - induced transformations and transformation - induced plasticity (TRIP) when it formed between Ms and Md temperature. In this paper, the heat - treat condition of this sort of low plain - carbon Si - Mn steel was investigated through observing the microstructure and examing the tensile properties. |
