Abstract

The overall goal of this project was to identify microstructures with optimised balance between strength, bendability and stretch-flangeability and to develop guidelines on how to produce this cold rolled sheet steel through three processing routes, i.e. by continuous annealing with gas cooling, continuous annealing with quenching, and the third route was hot dip galvanizing. The objectives were to produce material with the following properties: a tensile strength of more than 800 MPa, a hole expansion ratio (HE) of more than 35 % and a bending angle, Ri/t
