PRECIOUS METAL ALLOYS BASED ON THE NITIAU SYSTEM, WITH PHASE TRANSFORMATIONS IN SOLID STATE AND METHODS FOR THE PRODUCTION AND TRANSFORMATION THEREOF

摘要

There are described alloys based on TiAu and NiTiAu which present a reversible thermoelastic martensitic transformation. There are also provided particular treatment methods to obtain, among other things, surface colorations by means of controlled oxide formation.
