A combination of sputter coating and ion bean implantation will                 be used to produce beta phase intermetallic compounds on the                    surface of base metals.  The superelastic properties of the                     beta phase are expected to severely limit the nucleation and                    propagation of low cycle fatigue cracks.  In the first phase of                 the study, NiTi superelastic microalloys will be prepared by                    sputtering thin films onto Cu and Ni substrates.  Their                         composition, transformation temperature and crystallography will                be determined.  In the second phase of the study adherent films                 of superelastic material will be produced on base metal specimens               by ion beam mixing.  The effects on low cycle fatigue properties                will be studied.
