Abstract

Using the method of high-speed solidification of a hanging drop of a melt, discrete of the Ме–3TiC–2B4C, where Me is a metal Co, Ni or Fe. The microstructure of the alloy was studied, and mechanical properties of discrete fibers were obtained. To assess the effect of high-speed solidification of the melt on the properties of the alloys, cast samples were made without quenching. It was shown that the cobalt – based alloy in the initial state after quenching contains a metastable phase whit a face-centered cubic lattice, the proportion of which is 58 %. In addition, cobalt-based fibers contain metastable disperse intermetallic compounds of Co2B and Co3B.
