| Abstract Scope |
The weldability of high strength steels is often limited by control of the microstructure in the heat affected zone (HAZ), the region adjacent to the fusion zone, which experiences rapid heating and cooling rates, resulting is significant microstructural modification and commensurate property changes. To accelerate welding procedure development and qualification, simulative methods are needed to quantify microstructure evolution and identify desired welding and post weld heat treatment conditions. This work presents a framework for using a combination of thermo-mechanical physical simulations, autogenous gas tungsten arc welding experiments, and post weld heat treatment experiments to identify optimal welding process conditions. Using an example from a high strength supermartensitic stainless steel, the physical simulative methods are used to quantify the alloy phase transformation behavior, welding-induced property changes in the HAZ, thereby accelerating design of a welding procedure. |
