Abstract Scope |
The interface between dissimilar materials is crucial for overcoming performance limitations in aerospace and automotive applications. Gradient interlayers are essential for defect-free joining, as exemplified by the need to join Inconel 625 and Cu alloys in rocket engine combustion chambers. Choosing the right thermodynamic database and the associated quality evaluation are critical for efficient interlayer design using CALPHAD-based ICME (CALPHAD: Calculation of Phase Diagrams; ICME: Integrated Computational Materials Engineering) design modeling. This work provides a guideline with steps for evaluating thermodynamic databases, emphasizing their importance in compositional screening for dissimilar alloy joining. |
