Laser surface hardening (LSH) is one of the most widely used surface hardening process
which can be applied to almost the whole range of metallic materials in today's applications …

A predictive model for residual stresses induced in a laser hardened workpiece of AISI 4140
steel with no melting has been developed and experimentally verified. A transient three …

Laser surface hardening has become a promising replacement technique for conventional
heat treatment. The laser is a heat source, deployed with optics to modify the surface along …

Laser surface hardening is a promising technology to improve wear and fatigue properties of
steel surfaces. When the dimensions of the surface to be treated are larger than the cross …

A numerical model is presented for evaluation of residual stresses following laser surface
treatment of mechanical components with arbitrary geometry. Following on from previous …

The metallic materials such as steel, iron, titanium and nickel alloys etc., are extensively
