Abstract: One of the utmost challenges of hot aluminum extrusion is to design the die cavities with sharp corners (used to extrude thinwalled profiles) by considering the effective nitriding surface treatment of the die bearing ...

Abstract: Gas nitriding is a common surface treatment practice to improve the wear resistance of AISI H13 hot extrusion die cavities. However, due to the presence of complex and sharp features of die cavities, it has been observed ...
