摘要：
The paper examines bulk changes and evolution of the microstructure and phase composition in solid-phase sintering of titanium and TiAl3 powder mixtures. Metallography, x-ray diffraction, and electron microprobe analysis are used to ascertain the sequence of structural transformations during isothermal holding in sintering. Samples with high content of TiAl3 intermetallide powder substantially expand during sintering since TiAl3 particles dissociate leaving pores behind and TiAl particles grow pushing each other away.
