Abstract
The effect of Ru addition on the martensitic transformation and mechanical properties of
Zr50Pd50 xRux SMAs shape memory alloys has been studied. Strain–temperature experiments,
differential scanning calorimeter, and scanning electron microscope analyses were performed to
validate the theoretical predictions by DFT calculation regarding the influence of the C¢
parameter on martensitic stability. Despite the absence of an observed shape memory effect
under the tested conditions, the findings suggest that ZrPdRu alloys hold promise for
high-temperature applications.
