... and local stress-strain behavior controlled by thermomechanical conditions. Process modeling and simulation are important tools to evaluate thermomechanical and metallurgical conditions ( Ref 34 ). Early AM modeling research focused on DED processes, because the processes are similar to traditional weld...

... principal types. Primary carbides, which form when carbon reacts with strong carbide-forming elements such as tantalum and titanium during the solidification of the molten alloy, have the formula MC, where M is the metallic element. Typically, such carbides have a blocky or scriptlike morphology, as shown...

... where microporosity is expected can be predicted by solidification modeling, similar to the prediction of macroporosity. When the shrinkage and the gas combine to form macroporosity, properties are deleteriously affected. Static properties are reduced at least by the portion of the cross-sectional...
