Abstract

The characteristics of structural changes during heat treatment of Mo–Ti–Zr–С powder alloy obtained by spark plasma sintering were studied. The sintering conditions to obtain nearly theoretical density were worked out. The mechanical and physical characteristics like density, bending strength and plasticity were defined. In order to improve mechanical properties of the material and to obtain dispersion-strengthened structure the heat treatment was carried out. After this the material’s structure was investigated using optical and scanning electron microscopy and mechanical tests were carried out.
