In order to clarify the transformation sequence in Ti50.0Pd50.0-XFeX alloy in detail, in-situ heating TEM observations and electron diffraction experiments were carried out in JEM-2010 microscope equipped with omega type energy-filter. Mf temperature of Ti50.0Pd43.0Fe7.0 alloy is about 520 K and martensite of 2H and 9R structures are observed at room temperature. The 9R martensite directly reverts to the B2 parent phase via no intermediate state. Only incommensurate (IC) phase is confirmed at room temperature in Ti50.0Pd40.0Fe10.0 and Ti50.0Pd36.0Fe14.0 alloys, although Mf temperatures of these alloys are above room temperature. The IC phase transforms to the B2 parent phase without any shift of intensity maximum position of IC reflections with heating. Therefore, the low temperature phase in the alloys with more than 8.0 at% of Fe is the IC phase. Based on these results, systematical transformation phase diagram is proposed.
