Conclusions
The size of the relative phase interface of a finely divided tungsten-copper mixture provides a measure of the uniformity of distribution of the phases in the mixture. A mixture with a large phase interface is not prone to localization of densification during LPS. In the particle size range of the refractory phase ensuring the necessary level of capillary forces, a high starting degree of homogeneity of a mixture with a small concentration of the low-melting-point component is an essential condition of its effective densification during LPS.
