Analysis of Cracks in the Pulsed Nd:YAG Laser Welded Joint of Nickel-Based Superalloy
The weldability of GTD-111 nickel-based superalloy by pulsed Nd:YAG laser welding with an average power of 250 W was studied, and the microstructural evolution and cracking characteristics were also investigated. The solidification cracking of the fusion zone (FZ) and the intergranular liquation cracking in the heat affected zone (HAZ) were observed in the joint. Solidification cracking was cau...
متن کاملLaser Cladding of Ultra-Thin Nickel-Based Superalloy Sheets
Laser cladding is a well-established process to apply coatings on metals. However, on substrates considerably thinner than 1 mm it is only rarely described in the literature. In this work 200 µm thin sheets of nickel-based superalloy 718 are coated with a powder of a cobalt-based alloy, Co-28Cr-9W-1.5Si, by laser cladding. The process window is very narrow, therefore, a precisely controlled Yb ...
متن کاملthe effect of heat treatment on the microstructure of cast ni-based in100 superalloy
the purpose of this study was to investigate the effect of heat treatment including solution treatment and aging on the microstructure of cast nickel-based in100 superalloy including size, volume fraction and morphology of primary γ' and different kinds of carbides. for this purpose, different solution heat treatment cycles and a constant aging cycle were implemented on cast ingot samples and t...
متن کاملEffects of the Hot Isostatic Pressing Process on Crack Healing of the Laser Repair-Welded CM247LC Superalloy
This study investigated the effects of the hot isostatic pressing process on the crack healing, microstructure, and mechanical properties of the laser repair-welded CM247LC precipitation-hardened superalloy. To ensure the strength of the repair-welded area, this study used the direct re-melting approach, and simulated the repair welding with the filler addition, which has a chemical composition...
متن کاملA synchrotron study of microstructure gradient in laser additively formed epitaxial Ni-based superalloy
Laser additive forming is considered to be one of the promising techniques to repair single crystal Ni-based superalloy parts to extend their life and reduce the cost. Preservation of the single crystalline nature and prevention of thermal mechanical failure are two of the most essential issues for the application of this technique. Here we employ synchrotron X-ray microdiffraction to evaluate ...
