The most important concepts to apply a shape memory alloy in many
industrial applications is the composition design that controls the
transformation temperatures. In this paper, two mathematical models were
created to predict the transformation temperatures for poly-crystalline (Co-Ni-
Al) alloys. The data that was depend on to find the relation between chemical
composition and transformation temperatures were concluded from previous
work and approved by preparing samples in investigation practically. Four
different alloys were prepared to verify this relation. It was indicated that the
best criteria that present the chemical composition is the (e/a) and make the
alloy applicable for different applications. These suggested chemical
compounds could be controlled and adjusted according to heat treatment time.
