Metal alloys for medical devices
First Claim
1. A medical device that is at least partially formed of a metal alloy which improves the strength and ductility of the medical device, said metal alloy including at least about 90 weight percent of a solid solution of a rhenium and molybdenum alloy, said metal alloy including at least about 40 weight percent rhenium and at least about 40 weight percent molybdenum, said metal alloy having a controlled amount of nitrogen, oxygen and carbon so as to reduce micro-cracking in said metal alloy, a nitrogen content of said metal alloy less than a combined content of oxygen and carbon in said metal alloy, said metal alloy including an oxygen to nitrogen atomic ratio of at least about 1.2:
- 1, said metal alloy including a carbon to nitrogen atomic ratio of at least about 2;
