RISLaser Heat Treatment of Cast Irons—Optimization of Process Variables: Part I
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 1.2 kw CO2 -CW laser operating in ring and Gaussian beam modes was used to surface harden gray and ductile cast irons. The microstructure, case depth, hardness, surface integrity, and ...
Laser Heat Treatment of Cast Irons—Optimization of Process Variables, Part II
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ASTM class 40 gray and 80-55-06 ductile cast irons were surface heat-treated by a 1.2-kW, CO2 laser to study the effects of square and oscillating-gaussian beam modes on case depth, coverage ...
