The structure and mechanical properties (bending strength and bending deflection) of three alloys with high content of eutectic constituents were investigated. The formation of the structure is considered according to the Ti-Ga-Si phase diagram presented by the sections through the points of compositions of the alloys investigated. The mechanical properties have been determined by means of bending test of the samples by a scheme of the three-point bend in the air in the temperature interval of 20-800 degrees C. The correlation between the structure and mechanical properties is considered.
