摘要: AbstractThe influence of sulphur on microfissuring has been studied by characterising the hot ductility and heat affected zone (HAZ) in welded wrought Inconel 718. A series 718 base alloys, with concentrations range 7–110 wt-ppm lowest possible carbon, boron, phosphorus were used study. The alloys was measured using a Gleeble 1500 system, their weldability evaluated bead plate electron beam welding. effect weld HAZ compared that boron containing, but free, alloys. Sulphur reduced material, its very moderate comparison boron. rate increase brittle temperature parameter increasing concentration significantly smaller concentration. This may be because seem to i...
