摘要：

This paper presents the results of studying the production of molybdenum-tungsten alloys by spark plasma sintering at various process conditions, as well as the processes of material compaction and structure formation. A comparative analysis of compactability of molybdenum-tungsten alloys produced by spark plasma sintering and sintering in hydrogen was performed. It was shown that a relative density of > 95% can be achieved at a temperature of 1,800 degrees C and external pressure of 50 MPa.
