The effect of continuous galvanizing thermal cycle on the microstructure and mechanical properties of two multiphase TRIP-assisted steels

Multiphase TRIP assisted-steels are particularly attractive for the automotive industry, as they exhibit an exceptional strength-ductility balance which is attained through the combination of a complex microstructure and of a TRIP effect, i.e. the mechanically induced transformation of metastable retained austenite. This multiphase microstructure - and particularly the retention of metastable austenite - is obtained through the combination of …
