Intergranular Stress Corrosion Cracking growth perpendicular to fatigue pre-cracks in T–L oriented compact tension specimens in simulated Pressurized Water Reactor primary water

Intergranular Stress Corrosion Cracking (IGSCC) growth observed perpendicular to the plane of fatigue pre-cracks in T–L oriented compact tension specimens made of highly cold-rolled Type 316 stainless steel has been investigated metallurgically. One-directional cold rolling resulted in significant lamellar local strains on the plane parallel to the rolling plane. Oxide was detected along intergranular crack. It is deduced that intergranular...
