METHOD FOR SINTERING ARTICLES MADE OF POWDERS OF GROUP WC-Co SOLID ALLOYS Russian patent published in 2017 - IPC B22F3/12 C22C29/08 B22F3/87

Abstract RU 2636538 C1

FIELD: metallurgy.

SUBSTANCE: sintering articles of powders of WC-Co group solid alloys by electro-impulse pressing at pressure of 50-500 mpa, current pulse density of 50-500 kA/cm² and current pulse duration of not more than 10^-3 s followed by cooling. During cooling when the article reaches Curie temperature, it is subjected to magnetic-pulse treatment with field strength of 400-2000 kA/m for at least 0.01 s.

EFFECT: improved quality of products due to reduced structural non-uniformity and free energy of the article material.
