Abstract: In this work, the formability of HSLA (micro alloyed steel of 1.6 mm thickness) and EDDQ (1.2 mm thickness) steels have been studied and the suitability of HSLA and EDDQ steels for forming applications have been examined. The experimental work on microstructural aspects, tensile properties and formability parameters were carried out for both the steel sheet metals. The forming limit diagram for EDDQ and HSLA steels have been experimentally evaluated. A detailed analysis of the strain distribution profiles obtained from experiment has been attempted. The fracture surfaces of the formed samples have been observed using scanning electron microscopy with a view to obtain a correlation between fracture behaviour and formability of the sheet metals. The EDDQ steel has been found to possess good drawability and stretchability, whereas the HSLA steel has been found to possess limited drawability and stretchability.
