Abstract

The basic properties of the consolidated titanium powder materials obtained by two methods electrical pulse sintering and conventional vacuum sintering were investigated. Titanium powder consists of spherical and nonspherical forms and it has the particle size distribution 200 – 400 microns. Consolidated by two different methods powder composition consisting of 20–30 % nonspherical particles (else – spherical particles) has 5-7 times permeability higher than permeability just the spherical powder composition. Conventional vacuum sintering method allows manufacture a consolidated samples during 60 - 70 minutes at a sintering temperature of 1000 to 1200 degrees Centigrade. Electrical pulse sintering produces the samples with the same properties during 70 – 80 microseconds.
