It has been shown that when growing diamond single crystals in the diamond thermodynamic stability region using solvents based on iron-cobalt-zirconium alloys virtually all crystal faces exhibit microrelieves, which represent the combination of valle

The process of formation of composites in the Cu-Ti-Al system during thermoreaetive sintering has a diffusional character, and the resultant microstructure therefore consists of various intermetallic compounds and remains of the starting components.

The reaction between tungsten and copper in the presence of nickel under conditions close to those of pseudoalloy formation is characterized by the formation of a two-layer zone in the copper. Next to the tungsten there is a layer of a phase containi

The mechanism of structure formation in a titanium-nickel alloy of eutectic composition during sintering consists in the dissolution of nickel particles in a titanium matrix, which leads to the formation of the intermetallic compound TiNi and generat

The sintering of a chromium carbide composite is accompanied by the formation of a stable carbide (Cr, Fe)7C3, whose relative iron and chromium contents are determined by the chemical composition of the matrix phase and temperature. The relative amou

The addition of 2% P or B has no effect on the melting point of a Ti-Ni alloy of eutectic composition, 7% Si raises it by 50°K, and 10% Cu lowers it by 100°K. Alloying with boron and phosphorus does not alter the phase composition and structure of
