【摘要】：研究了不同退火工藝對SUS410L鐵素體不銹鋼熱軋板組織與力學(xué)性能的影響。結(jié)果表明:在600~800℃退火保溫10~30 min,隨著退火溫度、時間的增加,再結(jié)晶程度增加,強(qiáng)度降低,伸長率升高;在750℃退火保溫40~60min,隨著退火時間延長,力學(xué)性能變化不明顯;經(jīng)850℃退火后,鋼中有馬氏體生成,由于馬氏體相變強(qiáng)化作用,使得試樣的強(qiáng)度升高、伸長率下降;馬氏體顯微硬度為180~190 HV,鐵素體顯微硬度為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，
