Properties of high-dispersed Al-REE alloys produced by plasma recondensation
Properties of powders of alloys on the basis of the aluminium, alloyed REM, received by a method of plasma recondensation, and also of features of their not isothermal oxidation on air were studied. It is shown, that an input of process of oxidation with dispersity growth completeness and speed of interaction sharply increase. Along with oxides there is an aluminium nitride formation, and its quantity also increases in process of growth of dispersity of particles. The mechanism of oxidation of powders is defined by processes phase-formation in bed of products of interaction on a surface of particles.
