Due to its excellent biocompatibility and its ability to mimic biological forces, the medical implant industry has shown strong interest in expanding the application of NiTi SMAs. However, traditional SMA functional properties are limited by a single set of thermomechanical characteristics in a monolithic component. Past efforts in overcoming this limitation have had little success until recently with the invention of the multiple memory material (MMM) processing technology. This novel processing technology enables multiple functional responses through the augmentation of local microstructure and composition using a high power density source such as a laser. This thesis presents an investigation of the effect of laser processing on pseudoelastic behaviour and corrosion response of medical grade SMAs.enNitinollaser processingShape memory alloyspseudoelasticityMaster ThesisMechanical Engineering
