TiAl powder
TiAl powder
TiAl (γ-TiAl) alloy is a type of intermetallic compound mainly composed of γ-TiAl phase. It has low density (approximately 3.9–4.2 g/cm³), high specific strength, and excellent high-temperature oxidation resistance and creep resistance. It exhibits significant performance advantages in the range of 700–900 °C and is one of the important materials for achieving lightweight high-temperature structural components. Compared with traditional superalloys, TiAl can achieve about 30–50% weight reduction, showing significant application potential in aircraft engines and automotive turbocharging systems.
