| Research Abstract |
Au-28Pt alloy is a MR susceptibility-artifact-free alloy because its volume-magnetic-susceptibility is close to that of water(-9ppm, SI unit). By addition of Nb, a highly biocompatible metal element, the authors successfully developed artifact-free Au-xPt-8Nb alloy(x=5, 10) showing 50% higher hardness than Au-28Pt alloy. This alloy can be applied for various metal devices for biomedical applications requiring higher mechanical properties.
