Precipitates in the Ti46Ni37.5Pd16.5 alloy were investigated by electron diffraction and high-resolution scanning transmission electron microscopy. The phase content and stability were determined at several different temperatures and times. Aging at 400?C for an hour results in a new phase, which is consumed by P-phase at longer aging time. At 450?C, the new phase appears first, and then coexists with P-phase. At 500?C, the entire alloy transformed into the new phase. At 550?C, Ti3(Ni,Pd)4 phase begins to form.
