We investigate the transformation from B2 to B19/B19’ in the PtTi shape memory alloys using density functional theory within the generalized gradient approximation, VASP code [1]. We will present the results on the heats of formation, phonon dispersions and the density of states for the B2, L10, B19 and B19’ PtTi structures. Furthermore, we calculated the lattice expansion for the B2 and L10 PtTi structures.
