The invention relates to manufacture of titanium articles from sintered powders. The cost-effective initial powder: 10-50 wt % of titanium powder having &#x2266;500 microns in particle size manufactured from underseparated titanium sponge comprising &#x2266;2 wt % of chlorine and &#x2266;2 wt % of magnesium; 10-90 wt % of a mixture of two hydrogenated powders A and B containing different amount of hydrogen; 0-90 wt % of standard grade refined titanium powder, and/or 5-50 wt % of alloying metal powders. The method includes: mixing powders, compacting the blend to density at least 60% of the theoretical density, crushing titanium hydride powders into fine fragments at pressure of 400-960 MPa, chemical cleaning and refining titanium powders by heating to 300-900&#xb0; C. and holding for &#x2266;30 minutes, heating in vacuum at 1000-1350&#xb0; C., holding for &#x2266;30 minutes, and cooling.
