Advances in Metallic Materials for Medical Devices

摘要

The potential benefits of shape memory alloys (SMAs) are well-known and include high strain recovery, good actuation work output, sustained spring force, and high cycle fatigue capability. Properly-engineered binary Nitinol can often be designed to meet or exceed requirements where SMAs are warranted. In other cases, due to misconceptions, real limitations, or other philosophical constraints, plain Nitinol may not satisfy the design requirements. Here we discuss advances in materials science and engineering as applied to metallic materials for medical devices.
