Induction hardening is a selective heat treatment method that hardens the surface and sub-surface area of the part to the desired depth and keeps the metal core soft for toughness. Steel shafts and components made of medium carbon and alloy steel are mostly hardened using a semi or fullyautomated induction hardening machine. It is a […]

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
