An Introduction
Alpha and Near-Alpha Titanium Alloys are the traditional high temperature alloys. They have a near-single phase structure, giving them excellent creep characteristics, whilst offering the good strength of Alpha-Beta Alloys (up to 600MPa). The predominant alloying element in Near-Alpha Alloys is Aluminium, providing excellent strength and resistance to oxidation, at high temperatures. It was during the research into Near-Alpha Alloys that the detrimental phenomenon of Ti₃Al was discovered. The way this stress corrosion occurance is avoided is to cap Aluminium content at 6% for the standard alloys, although specialist alloys can still feature up to 9%. Included Alpha phase stabilisers in Alpha and Near-Alpha Alloys are Oxygen, Nitrogen and Carbon, whilst Beta isomorpheous and eutectic elements Molybdenum, Vanadium, Iron, Nickel, Hydrogen and Silicon also feature.
All grades, shapes and specifications of Near-Alpha Titanium Alloys are available directly through Integ Metals, so please feel free to read through the information on this page for reference, or contact us directly with your requirements.
