【摘要】：研究了不同退火工艺对SUS410L铁素体不锈钢热轧板组织与力学性能的影响。结果表明:在600~800℃退火保温10~30 min,随着退火温度、时间的增加,再结晶程度增加,强度降低,伸长率升高;在750℃退火保温40~60min,随着退火时间延长,力学性能变化不明显;经850℃退火后,钢中有马氏体生成,由于马氏体相变强化作用,使得试样的强度升高、伸长率下降;马氏体显微硬度为180~190 HV,铁素体显微硬度为130~140 HV。
[Abstract]:The effect of different annealing processes on the microstructure and mechanical properties of SUS410L ferrite stainless steel hot rolled sheet was studied. The results show that the recrystallization degree increases, the strength decreases and the elongation increases with the increase of annealing temperature and time for 1030 min, annealed at 600 鈩，
