Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

open access: yessteel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...
