The cubic B2 TiPt alloy was found to be mechanically unstable with a negative shear modulus compared to the commercially used TiNi. In addition, the alloy has been found to exhibit a low shape memory effect which is attributed to low critical stress for slip deformation compared to the stress required for martensitic transformation. To improve the mechanical properties of the TiPt alloys, the addition of Ni and Ta is investigated using the first principle approach. The stability of the alloys is studied in terms of their structural and elastic properties. In addition, the density of states for the alloys is presented.AbstractenTi-Pt alloysTi-Pt shape memory alloysFirst principle approachConference PresentationN/A
