35crmo无缝钢管变形是怎么回事

文章出处:http://robytone.com 发表时间:2019/4/20 14:34:26 点击:0

  今天我们来认识一下35crmo无缝钢管变形究竟是怎么回事:

  35crmo无缝钢管变形速度对塑性的影响是个比较复杂的问题.随着变形速度的增加,既有使方管塑性降低的一面,也有作用相反的一面。一般认为,当变形速度不大时,增加变形速度有降低塑性的作用;而变形速度增加较大时,塑性随变形速度的增加而提高,35crmo无缝钢管塑性随变形速度的增高而降低,可能是由于方管加工硬化及位错受阻而形成内裂所致。在该阶段虽然可以利用温度热效应促使金属软化,使塑性略有回升,但是在变形过程中,加工硬化发展的速度仍然大大超过金属软化的速度,从而使塑性下降。
