| 释义 |
In metallurgy, titanium gold (Ti-Au or Au-Ti) refers to an alloy consisting of titanium and gold. Such alloys are used in dentistry,[1][2] ceramics and jewelry.[3] Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength, hardness, and magnetism than either of its constituent metals.[4] In July 2016, researchers have discovered that a titanium-gold alloy, β-Ti3Au (strictly speaking, an intermetallic), is up to 4 times harder than titanium.[5][6] In popular cultureIn the 2008 film Iron Man (2008 film), the title character wears an armor made from a titanium-gold alloy.[7][8] According to actor Robert Downey Jr., who played the role of Iron Man, the suit fit him "like a gold-titanium glove".[9] Magnum Research's Desert Eagle comes in a titanium gold variant.
