Effects of Thermal Fatigue on Laser Modified H13 Die Steel

In order to improve wear properties of H13 die steel, Thermal fatigue properties of AISI H13 tool steel were investigated at varied number of cycles for enhance surface hardness. A CO2 laser system was used with 0.09 mm focused spot size on the sample surface. The parameter controlled were peak powe...
