一、前言关于延迟淬火对组织和性能的影响已有了较为深入的研究,延迟淬火工艺在工程上也有了不少应用。18Cr2Ni4WA钢的过冷奥氏体(A′)非常稳定,可将其“延迟”温度降
First, the preamble on the delayed quenching on the organization and performance have been more in-depth study, delayed quenching process also has a lot of engineering applications. The supercooled austenite (A ’) of 18Cr2Ni4WA steels is very stable and can have a “delayed” temperature drop
