3. Fatigue fracture performance
During the working process of the mold, under the long-term effect of the cyclic stress, fatigue fracture is often caused. The form has small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture.
The fatigue fracture properties of a mold depend mainly on its strength, toughness, hardness, and the amount of inclusions in the material.
