【摘要】：通过对自制的高强钢进行退火处理,研究了退火温度对高强钢组织和拉伸性能的影响。研究结果表明,当退火温度较低时,高强钢组织中主要为马氏体;随退火温度升高,马氏体逐渐向贝氏体和珠光体转变。当退火温度为850℃时,高强钢的拉伸强度为631.4 MPa,伸长率为22.6%。
[Abstract]:The effect of annealing temperature on the microstructure and tensile properties of self-made high strength steel was studied. The results show that when the annealing temperature is low, the microstructure of high strength steel is mainly martensite, and with the increase of annealing temperature, the martensite gradually changes to bainite and pearlite. When the annealing temperature is 850 鈩，
