Laser Surface Hardening of 51Crv4 Steel
(Universitatea "Dunărea de Jos" din Galați, 2005)
The work presents the surface changes in microstructure and properties by
quenching the 51CrV4 steel from liquid and solid phase, using a CO2 continue laser
wave with 900W power. In order to determine the hardening ...
