Assessment of the Fatigue Cracking Impact and Optimization of Operating Conditions of a Hydraulic Hammer Anvil

Two main cracks appear on the upper end of the inner hole of a hammer anvil after 130 hours’ impact. The fracture morphology, microstructure, metallographic microscopy results and nonmetallic inclusions of the cracked anvil are analyzed. The chemical composition and mechanical properties of the anvi...
