FORMATION MECHANISMS OF STRUCTURE AND OF PROPERTIES IN HIGH-ALLOY TITANIUM COMPOUNDS, WHICH WERE PRODUCED BY FAST HARDENING FROM MELT, ESTIMATION OF OPPORTUNITY TO CREATE ALLOYS WITH INTERMETALLIDE TYPE OF STRENGTHENING ON THIS BASIS

There the study objects are VT22 high-alloy titanium compounds, which were produced by the fast hardening in the melt by the microgranulation method. The purposes are to ascertain the formation mechanisms of structure and properties of granules of multiphase titanium compounds, to estimate the opportunity for the development of new class compounds with the intermetallide strengthening type. The new scientific information for the thermokinetics of metastable solid solutions during the heat treatment of titanium compounds with the intermetallide strengthening type opens the opportunity to create the new class of multiphase compounds. The recommendations to create the high-strength and high-temperature titanium compounds with the use of processes of granule metallurgy and of intermetallide strengthening type have been presented; the experimental compounds, which compare favourably with the traditional compounds in own characteristics, have been developed. VT22 granulated compound has been checked to produce the parts of engine and of airframeAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
