| Abstract: | Most commercialized coronary stents are made of 316L stainless steels due to its good combination of properties,and currently some new stents are made of cobalt-based alloy owing to its higher mechanical properties. However,the presence of high quantity of nickel and/or cobalt elements in these materials,which are known to trigger the toxic and allergic responses,has caused many concerns.Nickel-free austenitic stainless steels have been developed in order to solve these problems.In this paper,based on the d... |
