Perturbed angular correlation (PAC) method was applied to study the martensitic phase transition of the TiPd shape memory alloy doped with In, Hf, and Zr. The hyperfine interaction parameters and their concentration and temperature dependences for ^{111}In/^{111}Cd and ^{181}Hf/^{181}Ta probe atoms were determined. The influence of ternary element additions on the electric field gradients at Pd site was evidenced. A decrease of the martensite start temperature (M_{S}) and an increase of the width of the hysteresis loop (T_{H}) with an increasing concentration of the impurities in TiPd alloy was observed. These relationships are much stronger for In and Zr, than for Hf admixture.
