An Introduction

Beta Titanium Alloys, with their Body Centred Cubic (BCC) structure, are formed by the addition of sufficient Beta isomorpheous and eutectic stabilising elements Molybdenum, Vanadium, Iron, Niobium, Chromium and Hydrogen to Titanium and then solution treated and aged to lock in the Beta phase and prevent martensitic transformation under quenching. This creates an exceptionally strong alloy, with high hardenability, excellent forgeability and good cold ductility. Their strength and easy forgeability have helped them gain favour in the aerospace industry where they are employed to produce landing gear, helicopter rotor heads and airframes. Grade 21 has the added advantage of being resistant to aircraft fluids at all temperatures, so is used extensively in jet engines.
