Continued material development in the automotive has given rise to a new generation of HSLA grades which are characterized by excellent strength and high ductility levels.
Studies of microstructure changes in high strength CMnAlSi steel after austenitization show that it is not possible to obtain a fully austenitic region with the addition of Al or Si higher than about 1.5% and actually these two elements strongly stabilize ferrite.

Creep Life Prediction
Creep life prediction is of paramount importance in selecting the right material for certain engineering applications and in the most extreme cases can prevent component failure leading to catastrophic effects.
Such implications mean that there has been an important development to assist in predicting creep life for example, the Strain-Acceleration-Parameter (SAP), which connects creep curves directly to the minimum creep rate.
