摘要:

 为了研究锻造对4Cr5W2VSi热锻模具钢高温性能的影响,采用不同工艺对4Cr5W2VSi热锻模具钢进行了锻造试验,并与未锻造试验钢进行了显微组织、高温磨损性能和高温抗氧化性能的测试与对比分析。结果表明:锻造显著细化了试验钢材的显微组织,提高了试验钢材的高温磨损性能和高温抗氧化性能。随着始锻温度从1050 ℃增大至1150 ℃,试验钢材的高温磨损体积和高温氧化速率均先减小后增大,高温磨损性能和高温抗氧化性能均先提高后下降。与未锻造试验钢相比,在始锻温度为1100 ℃、终锻温度为900 ℃、锻造比为5的工艺参数下,试验钢材高温磨损体积改善比率达46%、高温氧化速率改善比率达67%,试验钢材获得了优异的高温磨损性能和高温抗氧化性能。

 In order to study the effect of forging on high temperature properties for 4Cr5W2VSi hot forging die steel, the forging tests of 4Cr5W2VSi hot forging die steel were carried out by different processes, and its microstructure, high temperature wear resistance property and high temperature oxidation resistance property were tested and compared with those of the unforged test steel. The results show that the forging significantly refines the microstructure of the test steel and improves the high temperature wear resistance property and high temperature oxidation resistance property of the test steel. 

When the initial forging temperature increases from 1050 ℃ to 1150 ℃, the high temperature wear volume and the high temperature oxidation rate of the test steel first decrease and then increase, and the high temperature wear resistance property and high temperature oxidation resistance property first increase and then decrease.Compared with the unforged test steel, under the process parameters for the initial forging temperature of 1100 ℃, the final forging temperature of 900 ℃ and the forging ratio of 5, the improvement rate of high temperature wear volume and the high temperature oxidation rate for the test steel reach by 46% and 67%, respectively. The test steels obtain the optimal high temperature wear resistance property and high temperature oxidation resistance properties.
