Yoo, M H

The anomalous increase in yield strength of Ni/sub 3/Al with increasing temperature is the basis for the superior mechanical properties of modern superalloys. It is also the key issue of recent research and alloy design of nickel aluminides. The purpose of this note is to point out the fact that the effect of elastic anisotropy on the temperature dependence of yield stress is equally important in interpreting the main feature of all the experimental data available on Ni/sub 3/Al.
