Abstract

Combustion of mechanically activated mixtures in 2Co–Ti–Al and Co–2Ti–Al is investigated, and alloys based on them are obtained by self-propagating high-temperature synthesis (SHS). Microstructural, X-ray, and differential-thermal studies are performed. A Heusler phase Co₂TiAl-based alloy is obtained for the first time by means of mechanical activation. Conditions for the mechanical activation of a reacting powder mixture for the formation of a single-phase material is experimentally selected.

Co-Ti-Al中机械活化混合物的自蔓延高温合成

摘要

研究了机械活化混合物在2Co-Ti-Al和Co-2Ti-Al中的燃烧，并通过自蔓延高温合成（SHS）获得了基于它们的合金。进行了微观结构，X射线和差热研究。首次通过机械活化获得了Heusler相Co ₂ TiAl基合金。通过实验选择用于形成单相材料的反应粉末混合物的机械活化条件。
