Abstract
Interest in the alloys of the titanium-nickel system is due to their attractive properties: the high strength of nickel-based alloys, the ability of intermediate phases based on Ti2Ni and TiNi to undergo amorphisation and hydrogen absorption, and the thermoelasticity of TiNi-based alloys. Ti-Ni alloys are resistant to oxidation and corrosion in most mild corrosive environments, and are used in chemical, medical and engineering applications. Here, we report on alloys in the Ti-TiNi-TiRu composition range of the Ti-Ni-Ru system, where ruthenium additions produce some interesting effects. Using phase diagrams and experimental results, the constituents of high temperature alloys and alloying processes are discussed.
