A new metastable crystalline phase of bcc structure was obtained in the Mo-Pd system by 200 key xenon ion beam mixing in the Mo34Pd66 and Mo30Pd70 multilayered thin films at relevant irradiation stages and its lattice constant was identified to be a(BCC)=4.13 angstrom. The real composition of the bcc phase was then estimated to be around MoPd2. The newly formed intermetallic compound with bcc structure gives evidence that MoPd2 could be an ordered intermetallic phase in the binary phase diagram. The possible formation mechanism of the metastable MoPd2 bcc phase was also discussed in terms of the atomic collision theory.
