The results show that the appearance of Widmanstatten structure,upper bainite and martensite in the structure of 20MnSi HRB is the main cause making the yield point disappear.
结果表明 :2 0 Mn Si热轧带肋钢筋中出现的魏氏组织、上贝氏体及马氏体组织是使屈服点消失的主要原因。
The main reason why mechauical propcrties of qutnched and tem-Pered hcavy part or 35CrMo steel,such as impact toughness and so on,are impossiblc to meetthe requirements is regarded as tbe presentation or the upper bainite in its microstructure.
本文总结了多年来有关35CrMo钢热处理的经验，认为35CrMo钢制大件调质处理后冲击韧性等力学性能达不到要求的原因主要是组织中出现较大量的上贝氏体。
The results show that upper bainite and grain boundary segregation of Si element result in embrittlement of the oil cylinder.
结果表明,上贝氏体和Si元素的晶界偏聚导致油缸变脆。
