Abstract: 
The high temperature tests mechanic properties of samples, producted by cold pressing of unannealed powder and vacuum sintering, were performed with a aim to investigate an influence of temperature and bands initial porosity at strength and plasticity. The results of high temperature investigations allowed to define the temperature intervals of hot extrusion sintered bars. The mode of hot extrude is found, the composition of special shlicer is developed.
