| Abstract Scope |
Electroslag and submerged arc welding are deposition processes with two distinct phases (slag and metal) and are promising methods for additive manufacturing utilizing minimally refined feedstocks which have significant amounts of nonmetallic material. The equilibrium elemental constitution of the slag and metal phases can be calculated, but the transient behavior of element transfer is not well-studied due to the numerous complex governing phenomena. Small-scale samples were subjected to controlled time-temperature profiles in simplified thermophysical simulations of welding conditions to determine the effects of time and temperature on the elemental development of slag and metal phases for 410 stainless, 4140, and plain carbon steel. The transient mass transfer of elements, reduction of oxides by carbon, microstructures, and interfaces are analyzed and discussed, along with future applications of these results. |
