Abstract

Several alloying additions were made to NiAl and the effect on physical properties was evaluated. The values obtained were compared to available data on NiAl and NiAl alloys. Negligible effects were observed on thermal expansion and dynamic modulus with the additions studied. The high thermal conductivity of NiAl can be advantageously utilized in many applications, and it was found that additions of Hf lowered thermal conductivity only slightly, while larger decreases were found with other additions. However for the NiAl alloys currently under consideration for applications, significant advantages in physical properties are still maintained over nickel-base superalloys.
