Comparison of deformation behavior of Al-TRIP and Si-TRIP steels

The research utilized TRIP steels with Al and Si compositions to understand the influence of Al and Si on austenite deformation behavior. Aluminum alloying increased the average C-content of retained austenite relative to Si-alloying. Aluminum alloying showed the higher mechanical stability of austenite and higher resistance to deformation induced martensite relative to Si-alloying.
