The excellent formability of TRIP steel is primarily attributed to the presence of residual austenite in its structure. As the material is formed, the residual austenite undergoes gradual transformation into hard martensite, which facilitates uniform deformation, resulting in a superior combination of strength and plasticity. This helps to resolve the challenge of balancing strength and plasticity. Additionally, TRIP steel boasts high impact absorption energy, high strength plasticity, and high n-value.
