【摘要】 以12Cr3WV低活性F/M钢材料为对象,研究了不同应变速率和实验温度对12Cr3WV低活性F/M钢材料的影响,利用金相显微镜对变形后的组织进行观察。实验结果表明,应变速率和变形温度对热处理过程中12Cr3WV低活性F/M钢材料的变形行为影响很大,变形温度不变时,奥氏体的动态再结晶程度随着应变速率的提高而呈现降低的趋势。更多还原

【Abstract】 The research in the process of heat treatment 12 Cr3 wv low activity F/M steel material deformation behavior has very important scientific significance. Based on 12 Cr3 wv low activity F/M steel materials in the research object, the experiment studied the different strain rate and temperature on the 12 Cr3 wv low activity of the F/M steel material, the influence of the organization to make use of metallographic microscope observation. The experimental results show that the strain rate and deformation temperature on the heat treatment process of 12 Cr3 wv low F/M active impact on the deformation behavior of steel material, deformation at constant temperature, degree of dynamic recrystallization of austenite as presents the tendency of decrease with the increase of strain rate.更多还原
