Analysis of the Influence of High Temperature Synthesis Parameters on the Structure Formation in the Mechanically Activated 3Ti+Al Powder Mixture

Abstract

The influence of basic high-temperature synthesis parameters on the process of structure formation in the mechanically activated powder mixture 3Ti+Al was investigated in the study. The synthesis was realized by the method of induction heating in the thermal explosion mode. The heating temperature of the mixture reached 1500°C during the solid state reaction. This temperature exceeded the adiabatic combustion temperature. The investigations of the phase structure formation processes were conducted by XRD methods. In order to obtain a Ti3Al single-phase compound, the optimal time-temperature parameters of the synthesis were determined.

Features of the Formation of Various Functional Coatings of SHS Mechanical Composites Using Gas Detonation Spraying Technology

“…An effective means to purposefully influence the structural state of the reaction mixture and the SHS parameters, providing the ability to control the mechanisms of phase and structure formation of materials in the synthesis process, is a preliminary mechanical activation treatment (MA) [8][9][10][11].…”

Influence of low dose γ-irradiation on the structural state of mechanically activated powder mixtures of Ti + Al

“…В настоящей работе в качестве объекта иссле-дования выбрана порошковая смесь Ti+Al [15][16], поскольку в последнее время алюминиды титана и сплавы на их основе находят широкое применение для конструкций и деталей, работа-ющих в экстремальных условиях, в том числе в атомной, авиационной, энергетической областях [17][18]. Это стимулирует исследование явлений, возникающих при взаимодействии материалов данной системы с радиационным излучением.…”
