摘要
The unique material properties of Nitinol, such as its shape memory effect, pseudoelasticity and bio-compatiblility, make it ideal for medical device applications. However, reported adverse effects during laser processing of Nitinol have severely impeded its deployment. The current article details some key findings associated with local phase conversion resulting from pulsed Nd:YAG laser processing of Nitinol (Ni-49.2 at.% Ti). Results revealed changes to room temperature phases of the processed metal when compared to the base material, which also affect the tensile properties of Nitinol. (C) 2010 Elsevier B.V.
