Reactions in Ti-oxide composites during extrusion

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    In specimens of Ti-oxide composites produced by extrusion at 950 (Ti-SiO2) and 1050°C (Ti-MgO and Ti-A12O3), reaction is observed between the titanium and the oxides, with the formation of new phases around the inclusions, namely, Ti5Si3, Mg2TiO4, and AlTi2, respectively, as well as TiO2 in Ti-SiO2 and Ti-Al2O3 composites. The microhardness of the metallic matrix of the composites investigated is much higher than that of pure extruded titanium, which may be attributed to partial dissolution of the oxides in the titanium during heating and extrusion.

  2. 2.

    In specimens of Ti-CaO composites extruded at 1050°C, no new phases are observed, and the microhardness of the matrix increases only slightly.
