Laser Beam Treatment of Nimonic C263 Alloy: Study of Mechanical and Metallurgical Properties
In the present research experiment was performed to study the penetration effect of laser treatment on Nimonic C263 alloy using 400 W fiber laser. The influence of input parameters on scanning bead geometry was examined and microstructures of the bead were investigated. The effects of laser beam diameter on laser treatment were studied and found to be significant during the laser beam treatment. Depth of penetration and width of heat affected zone (HAZ) increase with the increase in laser power. Micro-hardness of the Nimonic C263 alloys, after laser treatment, was investigated and found to be in the range of 250–285 HV, which is higher than the parent material. From this investigation, a very small heat affected zone (35–95 µm) was observed during laser beam treatment of nimonic 263 alloy. The good bead appearances and microstructures indicate that laser beam treatment of nimonic 263 alloys is feasible.
