Abstract

Metallography, X-ray diffraction, and electron microprobe analysis are used to study Ti-Si materials containing up to 25 at.% Si produced by vacuum sintering of titanium, silicon, and titanium silicide Ti5Si3 powder mixtures. The results of structural studies are interpreted to explain volumetric changes during sintering of samples with different original phase compositions. It is established that the replacement of silicon by titanium silicide in the powder mixtures with titanium results in a multiple decrease in the porosity of sintered composites.
