摘　　要：通过使用控制轧制和加速冷却技术来研究HSLA低碳贝氏体钢的微观结构和机械性能,并分别测试不同的冷却开始温度、冷却速率等工艺参数对钢板最终微观结构和机械性能的影响。同时利用光学显微镜和电子透射显微镜评估由多边形铁素体、珠光体、贝氏体和马氏体/残余奥氏体组成的复杂微观结构。Controlled rolling followed by accelerated cooling was used in laboratory simulations to study the microstructure and mechanical properties of HSLA low carbon bainitic steel. The effects of processing parameters,such as cooling start temperature and cooling rates, on the final microstructure and mechanical properties were studied. Optical microscopy and transmission electron microscopy were used to evaluate the complex microstructures consisting of polygonal ferrite, pearlite, bainite and martensite/retained austenite constituent.
