Master Sintering Curve of W-Mo-Cu Alloy Prepared by Electric Field Sintering

The master sintering curve (MSC) was developed for the densification description and prediction of W-Mo-Cu alloy sintered by electric field sintering. W-Mo-Cu compacts were sintered at a temperature of 975 degrees C, the pressure of 30 MPa, and heating rate of 25,75,125 degrees C/s, respectively. The MSC of W-Mo-Cu alloy was successfully constructed with the calculated value Q = 110 kJ/mol and experimental data (such as shrinkage data and sintering time and temperature) of the compact. The shrinkage response and the densification process of the compact were studied with the MSC. What is more, the densification of the alloy was verified and predicted by the MSC. The results show that the MSC is a promising strategy for predicting the densification evolution of the ternary alloy during sintering.
