基于组织控制的热成形方法基础研究

基于组织控制的热成形方法,是一种集材料和成形于一体的新成形方法。文章针对USIBOR1500超高强度钢板,采用单向拉伸实验方法,分析研究了材料加热温度对材料高温组织的影响,以及在不同的高温组织情况下,变形温度、变形速度、冷却速度对材料变形以及最终组织及性能的影响。探讨了影响材料成形性能及力学性能的关键影响参数,以及有效的控制方法,为实现材料与成形工艺的优化结合,推动新材料的开发提供帮助。

Research on the hot forming method with microstructure controlling

The hot forming method is a new method that integrates material and forming technology.The based on the tensile test,the effect of heating temperature on materials structure for USIBOR1500 is developed,and the influences of deformation temperature,deformation velocity and cooling velocity on deformation and material's final properties are studied under varies hot structure.In addition,the key parameters to determine material's formability and mechanical properties,and the controlling method are reduced,which is value to the development of new material and forming method.
