AISI D2 punch head damage: Fatigue and wear mechanism

The purpose of this work is to analyze the damage of AISI D2 punch head whose main part is used halting production. The punch head failure could be categorized into three major types namely the swollen, the mated and the cracked punch. Furthermore, this study underlines the punch damage causes using the optical microscope and SEM so as to check and characterize the microstructure of cracks. In this respect, EDS was used to inspect corrosion,...
