The ability to advance model phase transformations in metals during welding enables design engineers to optimize material selection and joining processes in the earliest stages of product development. Techniques based on certain analytical equations can predict phase transformations. These methods are part of EWI’s overall ICME approach* to material behavior modeling. EWI associates Alber Sadek,...

Manufacturing engineers need tools that can help them understand microstructural changes during processes like welding, additive manufacturing, and heat treatment. Some available techniques (analytical, empirical, FEA) have been discussed in EWI’s recent ICME series* of papers. An additional approach uses phenomenological modeling to provide information important to predicting metallurgical behavior. EWI associates Rafael Giorjão and...

Weld thermal history, which greatly affects material microstructure especially in the heat affected zone (HAZ), can be difficult to predict accurately. As part of its ICME approach to predicting microstructural behavior in welding steels, EWI employs welding thermal cycle data -- welding parameters, materials chemical composition, joint design, and materials thickness as baseline inputs --...
