Effect of the initial microstructure and thermal path on the final microstructure and bendability of a high strength ferrite-martensite dual phase steel

The combined effects of the initial microstructure and heating rate on ferrite recrystallization, austenite formation and transformation kinetics of a regular ferrite-martensite dual phase steel are investigated. Special attention is given to the effect of the martensite distribution on mechanical properties, particularly the bendability....
