Abstract
The mechanism of formation of carbon- and gas-containing metallurgical macrodefects in titanium alloys and the mechanism of modification of these defects in the processes of smelting and heat treatment are established. As the main investigation method, the nuclear microanalysis was used, which allowed measurements of concentration distributions for oxygen, nitrogen, and carbon atoms in the zone of macrodefects. It is found that the source of carbon-containing macrodefects was fragments of a cutting tool. As a source of gas-containing macrodefects, the Ti-O-N particles served, which possess the liquidus temperature exceeding the temperature of smelting.
