【摘要】：通過對韌-脆轉(zhuǎn)變溫度及沖擊斷口的韌-脆斷裂轉(zhuǎn)變趨勢的分析,研究了Cr-Co-Mo-Ni軸承鋼經(jīng)不同溫度固溶熱處理后的韌-脆轉(zhuǎn)變溫度及其影響因素。結(jié)果表明:在1 000、1 030和1 060℃固溶,其韌-脆轉(zhuǎn)變溫度為100℃以上,在1 090℃固溶,韌-脆轉(zhuǎn)變溫度為70℃,且在-50℃鋼的沖擊功能保持在47J以上,1 120℃固溶,韌-脆轉(zhuǎn)變溫度為52℃,且-50℃的沖擊功為46J以上。隨固溶溫度的增加,原始晶粒增大,韌-脆轉(zhuǎn)變溫度卻降低,這是晶界處大顆粒M6C碳化物導(dǎo)致。
[Abstract]:Based on the analysis of ductile-brittle transition temperature and ductile-brittle fracture transition trend of impact fracture, the ductile-brittle transition temperature and its influencing factors of Cr-Co-Mo-Ni bearing steel after different temperature solution heat treatment were studied. The results show that the ductile-brittle transition temperature is over 100 鈩，
