摘要

Existence of back tempered regions in laser hardened materials is a common industrial problem. As a result of back tempering, the areas have lower hardness compared to hardened areas, becoming a potential breakage starting point. In this research Laser hardening is applied to AISI 1060 work piece to analyze relationship between laser beam parameters and back tempered region. Analytical model for thermal cycle similar to experimental condition is built and results from experiment and modeling are compared.
