摘要用连续退火模拟试验机，在实验室试制了冷轧高硅DP590，并通过扫描电镜、EBSD、透射电镜和力学性能测试研究了不同退火温度（735~835℃）对其组织和力学性能的影响。结果表明：退火温度对高硅双相钢强度和塑性有重要的影响，当退火温度为785℃时，材料获得良好的综合力学性能。不同温度退火后得到的组织均为铁素体和均匀分布在其晶界上的岛状马氏体；利用EBSD技术清晰地观察到离散分布于铁素体和马氏体晶界处的残余奥氏体。运用透射电镜观察到马氏体周围的位错线及位错团，这是双相钢连续屈服特性的重要保障。

Abstract：High silicon 590MPa grade cold rolling dual phase steels were trial-developed in laboratory with continuous annealing simulation tester. The effect of different annealing temperature(735 to 835℃) on the microstructure and mechanical properties were research by the SEM, EBSD , TEM and mechanical performance test. The results indicate that annealing temperature has important influence on strength and plasticity. When the annealing temperature is 785℃, material has the well mechanical properties. The microstructures of different annealing temperatures are the same. All of them are ferrite and uniformly distributed martensite on the grain boundaries of ferrite; discrete distribution of austenite in ferrite and martensite grain boundaries is clearly observed used EBSD technology. In addition, dislocation and dislocation roll around the martensite is found by TEM. And it is the important guarantee of continuous yield characteristic of dual phase steels.

Key words： high Silicon dual-phase steel annealing temperature microstructure mechanical properties
