Thermal aging effects on the microstructure of Nb-bearing nickel based superalloy weld overlays using ultrasound techniques
Secondary phases such as Laves and carbides are formed during the final stages of solidification of the nickel based superalloy Inconel 625 coatings deposited during the gas tungsten arc welding (GTAW) cold wire process. However, when aged at high temperatures, other phases can precipitate in the mi...
