Description

Intermetallics based on ordered γ-TiAl are being considered for the replacement of steels and nickel-based superalloys for high temperature aerospace and automotive applications. This study investigates the creep behavior of investment cast Ti-48Al-2Nb-2Cr with microstructures ranging from duplex to nearly lamellar. Constant load creep tests were conducted in air at temperatures of 650 C and 760 C and at stress levels of 104MPa, 155MPa, and 207MPa. The effects of cooling rates during casting, aluminum content, oxygen level, and microstructure on creep properties are discussed. The activation energy for creep and stress exponent are also reported
