Welding between Fe and Al alloys is difficult because of a significant difference in thermal properties and poor mutual solid-state solubility. This affects the weld microstructure and causes the formation of brittle intermetallic compounds (IMCs). T

FEM model for TIG hybrid laser butt welding of 6 mm thick austenitic to martensitic stainless steels
Publikováno v:
Procedia CIRP. 88:116-121
In this work, the finite element method (FEM) was employed to simulate hybrid laser TIG butt welding on 6 mm thick austenitic stainless steel (AISI 304) and martensitic stainless steel (AISI 410). These steels have received lot of interest from many
