Abstract

 
 
 In this study, the possibility of using of the following technogenic raw materials to obtain a composite material was considered: titanium-containing slag, with the addition of aluminum bronze grade PG-19M-01 (TU 48-4206-156-82) and aluminum powder grade PA-4 (GOST 6058-73). The percentage of components in the mixture were as follows (wt. %): slag - 40, PG-19M-01 - 30, PA-4 - 30. A thermodynamic simulation of the selected system was preliminarily carried out using TERRA program in the temperature range 273 - 4273 K. The chemical and granulometric composition of the initial powders was investigated. From the powder mixture there were compressed the tablets and then they were sintered in an inert atmosphere. Micro-X-ray analysis of sintered samples showed that they consist of large particles of various shapes, most likely containing titanium and iron aluminides, their compounds between themselves and with copper.

Highlights
This work is devoted to investigation of the possibility of using of technogenic raw materials - titanium-containing slag, with the addition of aluminum bronze grade PG-19M01 (TU 48-4206-156-82) and aluminum powder grade PA-4 (GOST 6058-73), to obtain a composite material
When implementing a sustainable controlled process, it is often necessary to vary the input parameters: initial composition, temperature, pressure, etc. The selection of these parameters can be largely carried out using thermodynamic calculations, which can significantly reduce the amount of experimental research and, thereby, reduce the time and material costs for testing the process
Peculiarities of behavior and temperature intervals of the existence of the main components of the condensed and gas phases formed during equilibrium heating are revealed
Summary
This work is devoted to investigation of the possibility of using of technogenic raw materials - titanium-containing slag, with the addition of aluminum bronze grade PG-19M01 (TU 48-4206-156-82) and aluminum powder grade PA-4 (GOST 6058-73), to obtain a composite material. It was supposed to produce a composite material consisting of particles of intermetallic compounds based on titanium, iron and aluminum, located in a soft, plastic matrix, providing the subsequent molding of the composite in the form of a wire This wire can be used to obtain a powder material or plasma spraying of coatings hardened by intermetallic particles and not requiring the application of an additional sublayer. When implementing a sustainable controlled process, it is often necessary to vary the input parameters: initial composition, temperature, pressure, etc The selection of these parameters can be largely carried out using thermodynamic calculations, which can significantly reduce the amount of experimental research and, thereby, reduce the time and material costs for testing the process. The thermodynamic properties (standard enthalpies and entropies of formation, temperature dependences of heat capacities, enthalpy increment H2098 − H00) were calculated using various methods, [see, for example, [18–21])
