摘要: 本文研究了动态应变时效预处理对18-8型奥氏体不锈钢高温(300~600℃)抗拉强度、疲劳强度和持久强度的影响。结果表明,动态应变时效预处理提高了材料的高温强度,且其强度随预应变温度和预应变量的增加而提高,动态应变时效具有比冷变形处理更优的强化效果。

Abstract: Effects of various dynamic strata aging pro-treatments on the static tensile strength, fatigue strength and creep rupture strength of an 18-8 type austenitic staialess steel at high temperature (300~600℃) were investigated. The results show that dynamic strain aging pre-treatment processes increase the high temperature strengths of the material, and the strength vales increase with increasing the prestrain temperature and prestrain. It is also found that the strengthening effect of dynamic strain aging is better than that of cold-working processes at the same prestrain.
