abstract="Phase equilibria in the Ti-corner of the Ti-Zr-Si system were studied by the methods of metallography, differential thermal analysis, X-ray and microprobe analyses of as-cast samples. The results are given in the way of the melting diagram and of polythermal sections at 10 and 20 at.% Si. At 1300 C invariant four-phase equilibrium of eutectic type L ↔ (β-Ti)(β) + (Ti5Si3)(Z) + ((Ti, Zr)2Si) (S2) was shown to occur in the concentration interval studied. The location of the eutectic point E was determined to take place at ∼78Ti-11Zr-11Si. The ternary compound S2 formed from the melt by peritectic reaction L + Z → S2. Microhardness of the primary suicide grains and of eutectics microconstituents has shown that zirconium additions decrease the strength of the Z-phase and of the β+ Z eutectic, while they do not change the strength of the S2-silicide and of the β+ S2 eutectic. Based on the results of hot hardness measurements, below 550°C he potential for attractive high-temperature structural properties is controlled by refinement of the microstructure, while above this temperature the α ↔ β transformation temperature of Ti limits the application. © 2004 Elsevier B.V.
