In this paper, potentials of accumulative roll bonding (ARB) severe plastic deformation (SPD) method to process effective nickel titanium alloys for biomedical application is presented. Effective material properties of biomedical NiTi alloys, including ultra-fine grain microstructure, functional, mechanical, wear and corrosion resistance were highlighted and discussed. Performance and challenges of other SPD methods in the literature have been reviewed and compared to that of ARB. Existing challenges, advantages and recommendation of using ARB to process NiTi alloys with desired properties for biomedical applications are given.
