已知相变诱发塑性（TRIP）钢中的铬通过增加在亚温热处理期间引入的奥氏体的可淬性而对机械性能具有不利影响。在这项研究中，它被认为是Al除了可以抵消Cr的影响，通过鼓励铁素体的形成在快速冷却和等温淬火。这有助于确保奥氏体的热稳定性，并恢复TRIP钢的优异机械性能，即使添加Cr。
Chromium in transformation-induced plasticity (TRIP) steel is known to have a detrimental effect on the mechanical properties by increasing the hardenability of austenite introduced during intercritical heat treatment. In this study, it is suggested that an Al addition can counterbalance the effect of Cr by encouraging ferrite formation during fast cooling and austempering. This contributes to securing the thermal stability of austenite and to retrieving the excellent mechanical properties of TRIP steel even with the addition of Cr.
