Abstract

In the present work it is shown that by means of directional crystallization of molibdenium dicilicide (MoSi2) based pseudobinary compositions with some refractory compounds, in particular with titanium diboride (TiB2), zirconium diboride (ZrB2), molibdenium boride (Mo2B5), boron (B4C) and silicon carbides (SiC) it is possible to produce composite materials with improved, as compared with pure molibdenium dicilicide, mechanical properties and high-temperature properties, such as oxidation resistance and thermal resistance.
