Titanium Beta C : ウィキペディア英語版 | Titanium Beta C Titanium Beta C refers to Ti Beta-C, a trademark for an alloy of titanium originally filed by RTI International.〔http://rtiintl.s3.amazonaws.com/RTI-Reports/tiguideWeb.pdf〕 It is a metastable "beta alloy" which was originally developed in the 1960s; Ti-3Al-8V-6Cr-4Mo-4Zr, nominally 3% aluminum, 8% vanadium, 6% chromium, 4% molybdenum, 4% zirconium and balance: titanium. ==Properties==
Beta C is relatively easy to melt and process during fabrication, when compared with other beta alloys. It is not recommended in high-wear applications due to its tendency to gall. Beta C has good corrosion resistance to both saline environments and acids, due to the properties of titanium and to its ability to spontaneously form a well adhered protective oxide layer when exposed to a high oxygen environment. Beta C is one of the least dense beta alloys, which combined with its ability to achieve high strengths through heat treatment provides a good strength to weight ratio. It is also capable of consistent high strength through relatively large section thicknesses.
