MODELING OF STRUCTURE FORMATION IN MIXTURES USING THE METHOD OF SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS

An investigation is made of the specifi c features of compaction of thin layers consisting of monodisperse calibrated solid balls that model a bidisperse powder mixture of large metallic and fi ne nonmetallic particles used for fabricating layer-by-layer compressed long-measuring blanks intended for the production of high-melting materials by the method of self-propagating high-temperature synthesis. Consideration is given to the case of one-sided axial compression of thin layers of balls in a matrix of hexagonal cross section at the ratio of the cross-sectional dimension of the matrix to the ball diameter equal to L/d ≈ 15.
