| 摘要 |
The invention relates to a high-temperature alloy for a mechanically highly stressed component of a thermal machine based on doped TiAl and a method to improve a mechanical property of the alloy. The alloy has the following composition (in atomic %): 44.5 to <46 Al, 1-4 W, 0.1-1.5 Si, 0.0001-4 B, and the rest Ti and contaminations due to the manufacturing process. The alloy is characterized by improved heat resistance and ductility at high temperatures, and at the same time good oxidation and corrosion resistance.
