The joint effect of Si (5,7,and 10 at.%) and at.%) on the structure and mechanical properties of Ti-rich as-cast Ti-Si-Sn alloys is studied. Hypoeutectic alloys with 10 at.% Si are shown to possess the highest level of properties due to a greater volume fraction of the (β*) + Ti 5 Si 3 . eutectic. It is shown that the dependence of strength and hardness of Ti-Si-Sn alloys onSn content is nonmonotonic. The properties improve with increasing tin content to 7-10 at.% due to the solidsolution hardening mechanism. The elastic modulus and plasticity of all the alloys decrease with increasing Sn content. The elastic modulus for the alloys with 7-15 at.% Sn almost halves, decreasing to 65-60 GPa. The level of long-term hot hardness of the alloys at different temperatures depends on Si and Sn content. In general, tin additions increase heat resistance of all the alloys studied. The deviation from the dependence for individual alloys results from variation in their phase composition. The mechanical behavior of Ti-rich Ti-Si-Sn alloys depending on Sn content is determined by the formation of the intermetallic Ti 3 Sn phase.

Abstract:The present paper provides a rewiev of our results on the phase equilibria and phase reactions in theTi-corners of the Ti-Si-{Al,Sn,Zr}, Ti-Si-Al-{Ge,Sn,Zr} systems. The relation between the character of the phase diagrams, the crystal structure of the phases, mechanical properties of the individual phases and materials are discussed. It is shown that a basic understanding of phase equilibria can provide useful guidance for the selection and development of alloys for high temperature structural applications.Key words: phase diagrams, phase transformations, structure, properties INTRODUCTIONThe Ti-Si binary phase diagram (Fig. 1) represents a prospective basic system for development of high temperature alloys with a combination of strengthening mechanisms. Mechanical properties of these materials depend on the topology of the appropriate phase diagrams in the concentration intervals of interest. Systematic information is absent on many relevant multicomponent phase diagrams based on the Ti-Si binary system. Thus, the goal of this paper is to present new results on phase relationships in the ternary and quaternary Ti-Si-{Al, Sn, Zr} and Ti-Si-Al-{Ge, Sn, Zr} systems, as well as to discuss some examples of the relation between the details of the phase diagrams with the properties of individual phases and materials.
