A microstructural study of HAZ cracking in conventionally and directionally cast polycrystalline and single crystal IN-738 LC
IN-738 LC, a precipitation hardened nickel based superalloy, containing substantial amounts of Al + Ti contents, is very difficult to weld due to its high susceptibility to HAZ cracking, during welding via conventional fusion welding techniques and subsequent PWHT. The cracking is mainly intergranul...
