Effect of Cold Rolling on the Microstructure and Texture of Selective Laser Melting Built Fe-Ni-Cr Steel

Incoloy 800 is an iron-based Ni-Cr super-austenitic stainless steel that finds applications involving exposure to high temperatures and corrosive environments. This study aims to investigate the effect of cold rolling on the microstructure, texture and hardness of Incoloy 800 fabricated by selective laser melting. Rectangular specimens of 100 × 20 × 5 mm were printed in the vertical build orientation. The as-built alloy was subjected to unidirectional cold rolling along the long transverse plane to achieve thickness reductions of 20, 40, 60 and 80
