Experimental investigation and finite-element modeling of the short-time induction quench-and-temper process of AISI 4140

摘要

Induction hardening is a widely used surface treatment technique that has extensively been investigated. In contrast, induction tempering with short heating times <= 1 s has not been investigated thoroughly, nor by experiment neither by simulations. Also, the influence of rapid tempering on the residual stresses after induction surface hardening has only been investigated superficially.
