critical quenching rate

Three concepts,critical quenching velocity,critical quenching pressure and quenching parameter,have been put forward.

提出了临界淬熄速度、临界淬熄超压和熄爆参数3个概念,用火焰传播速度和压力来描述抑爆效果,使用熄爆参数来衡量抑爆结构抑制燃烧爆炸的能力。

Bainite ferrite and retained austenite are obtained through austempering immedidely after inter critical annealing in dual phase steel containing C,Si and Mn.

新型 TRIP复相钢仅含 C、Si、Mn等合金元素 ,采用临界区等温淬火热处理工艺 ,获得铁素体、贝氏体和残余奥氏体三相组织。
