Superficial Hardening with Pulse Laser Applied to ASTM A537 HSLA Steel

Abstract

The surface hardening with YAG:Nd pulse laser is used to obtain a set of surfaces with different properties and it is based on the formation of a very fine martensite. The paper has been elaborated based on laboratory experiments on samples of A537 (HSLA steel).
