В настоящей работе изучалось влияние агентов управления технологическим процессом на морфологию и структурно-фазовое состояние порошковых смесей системы Ti-Al-Nb. Для совершенствования методики измельчения порошковых смесей системы Ti-Al-Nb в планетарно-шаровой мельнице были приготовлены два вида порошков с добавлением агентов управления технологическим процессом на основе стеариновой кислоты и жидкого толуола. Процесс измельчения составов с добавлением агентов проводили при 550 об/мин в течение 30, 60, 120, 180 минут.

В ходе исследований было установлено, что эволюция морфологий частиц с применением стеариновой кислоты и жидкого толуола имела схожий характер. Эффект агента как регулятора процесса стеариновой кислоты на эволюцию морфологии порошков был больше, чем у жидкого толуола, поскольку он более эффективнее ингибировал процесс холодной сварки порошков. При высокоэнергетическом измельчении с применением толуола в течении 120 и 180 мин образовываются нежелательные карбидные фазы.

In this work, the influence of process control agents on the morphology and structural-phase state of powder mixtures of the Ti-Al-Nb system was studied. To improve the technique for grinding powder mixtures of the Ti-Al-Nb system in a planetary ball mill, two types of powders were prepared with the addition of process control agents based on stearic acid and liquid toluene. The process of grinding the compositions with the addition of agents was carried out at 550 rpm/m for 30, 60, 120, 180 minutes.

During the studies, it was found that the evolution of particle morphologies using stearic acid and liquid toluene was similar. The effect of the agent as a process regulator of stearic acid on the evolution of powder morphology was greater than that of liquid toluene, since it inhibited the cold welding process of powders more effectively. During high-energy grinding using toluene for 120 and 180 minutes, undesirable carbide phases are formed.
