Thermal Modes of Synthesis in Mechanoactivated Powder Mixture Ti + Al
摘要
Abstract
In the presented work, a study of thermal synthesis regimes in mechanically activated powder mixture of Ti + Al was carried out. The possibility of the reaction realization in a low-temperature mode (up to 700°C) in a relatively short time (about 30 min) has been established. In this case, the composition of the synthesis products is identical to the composition of the synthesis products carried out in the traditional thermal explosion mode at a maximum temperature of 1300°C. The possibility of a relatively fast reaction in a low-temperature regime is determined by solid-phase diffusion under favorable condition due to the large surface area of contact of the reagents and a low energy diffusion barrier.
