Abstract

In this work, the effect of mixing time in a ball mill on the homogeneity and properties of molybdenum-tungsten powder mixtures was investigated. Consolidation of materials was carried out by spark plasma sintering. From the obtained compacts, samples were made for investigated the strength and plastic properties of materials. Optical and scanning electron microscopy was used to the analysis of the microstructure. Energy dispersive microanalysis was used to assess the elemental composition of the samples. The fractures of the samples were investigated.
