Heat treatment of D2 and H13 Tool Steel

The effects of austenitizing and tempering temperatures on the microstructure, as-quenched and tempered hardness capability, and Charpy V-notch impact resistance of D2 and Hl 3 tool steels were investigated. Decarborization behavior of D2 and Hi3 tool steels was observed by heat treating the samples in vacuum and normal furnaces. Heat treatment in an open atmosphere …

Ultrasonic Technology for Induction Case depth inspection

Introduction: Induction hardening is a case hardening process that improves the wear resistance, surface hardness, and fatigue strength of parts under dynamic and/or thermal stresses by creating a hardened surface layer while maintaining the unaffected softcore. This hardened layer, in part, is an essential quality characteristic of the induction hardening process. However, to evaluate the …
