Effect of ball milling on reaction betwe

This study investigates the effect of ball milling on the reaction temperatures of titanium dioxide and aluminum powders, aimed at producing titanium aluminide intermetallic compounds. The objective is to enhance the synthesis process of γ-TiAl materials, which offer advantages over traditional Ni-based alloys due to their lower weight and significant heat resistance. Utilizing a Fritch model planetary ball milling machine, titanium dioxide and aluminum powders were milled at various durations, and the resulting composite powders were analyzed via X-ray diffraction (XRD) and differential thermal analysis (DTA). Results indicate that the milling process influences the reactivity and reaction temperatures, with the formation of intermetallic compounds observed at critical temperatures during thermal analysis. The findings contribute to optimizing production processes for titanium aluminide materials, potentially reducing costs and expanding their applications in high-performance industries such as aerospace and automotive sectors. This research supports the broader use of titanium aluminide in applications where weight savings and heat resistance are crucial. The successful synthesis through this method may lead to more economical production practices in the future.
