TiAl Yet its modest melting point (1500C) precludes it from use in hightemperature blades and restricts it to the low-pressure turbine and static parts of the engine. After more than 20 years of effort on TiAl,8¨C11 it is not yet used in commercial jet engines, The problems that remain include low roomtemperature ductility (1¨C2%), low fracture toughness, high stress-sensitivity of fatigue life, and high manufacturing cost for finished parts. |
