Outline of Final Research Achievements

The workability of MRI artifact free Au-xPt-8Nb alloys, the auther have development, is insufficient for some type of biomedical devices. The authers have developed new Au-Pd based ternary alloys by adding a third element X exhibiting. Au-Pd-X alloys indicate MRI artifact free on Pd=10-26mass% and have good workability and are suitable for Biomedical devices requiring high-workability materials.
