This paper describes the effect of silicon on the manufacturing process, structure, phase composition, and selected properties of titanium aluminide alloys. The experimental generation of TiAl-Si alloys is composed of titanium aluminide (TiAl, TiAl or TiAl) matrix reinforced by hard and heat-resistant titanium silicides (especially TiSi). The alloys are characterized by wear resistance comparable with tool steels, high hardness, and very good resistance to oxidation at high temperatures (up to 1000 °C), but also low room-temperature ductility, as is typical also for other intermetallic materials. These alloys had been successfully prepared by the means of powder metallurgical routes and melting metallurgy methods.
本文描述了硅对铝化钛合金制造工艺、结构、相组成及选定性能的影响。TiAl-Si合金的实验生成物由硬质且耐热的硅化钛（尤其是TiSi）增强的铝化钛（TiAl、TiAl或TiAl）基体组成。这些合金的特点是耐磨性与工具钢相当、硬度高、在高温（高达1000°C）下具有非常好的抗氧化性，但室温延展性低，其他金属间化合物材料也有这种典型情况。这些合金已通过粉末冶金路线和熔铸冶金方法成功制备出来。
