The hot deformation behavior of ternary Ni-42.5Ti-3Cu alloy was modeled. Hot compression tests were carried out at the temperatures from 800°C to 1000°C and at the strain rates of 0.001 s−1 to 1 s−1. The experimental results were then used to determine the constants for developing constitutive equations. There was an unacceptable fitting between the predicted and experimental results

At the same strain rate the flow stress decreases with the increasing of the temperature. As the strain rate is less than 1.002s 611 there exist peak stress and steady flow stress and only peak stress appears at 10.002s 611 . The processing maps of C276 superalloy in different strains were constructed according to DMM model.

Heavily codeformed two-phase materials can show anomalous increases in strength as a function of the level of deformation. The strength of these materials can vary considerably from what is predicted by the rule of mixtures. Understanding the mechanisms responsible for the strengthening of these materials can lead to the better understanding of the strengthening of the individual phases and
