【摘要】：通過對(duì)自制的高強(qiáng)鋼進(jìn)行退火處理,研究了退火溫度對(duì)高強(qiáng)鋼組織和拉伸性能的影響。研究結(jié)果表明,當(dāng)退火溫度較低時(shí),高強(qiáng)鋼組織中主要為馬氏體;隨退火溫度升高,馬氏體逐漸向貝氏體和珠光體轉(zhuǎn)變。當(dāng)退火溫度為850℃時(shí),高強(qiáng)鋼的拉伸強(qiáng)度為631.4 MPa,伸長率為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，
