Analysis of liquation and solidification cracks in the electron beam welding of GTD-111 nickel-base superalloy joint
The weldability of GTD-111 superalloy by electron beam welding was studied, and the cracking evolution of solidification and liquation, as well as microstructural characteristics, were also investigated. The weld metal microstructure consisted mainly of the inter-dendritic phases of MC, γ - γ′ and γ...
