Owing to their low density and high strength, titanium alloys are extensively used in the aerospace industry. As the amount of aluminium in the alloy is increased, it is known to undergo a change in the structure, from a completely random state to an ordered state. This transition is known to radically affect the physical properties of the material, in particular its strength. Prior to the formation of this ordered state there is a noticeable change in the properties that has been explained by the formation of locally ordered regions, although overall the material is still considered to be disordered. Through this experiment we hope to characterise the nature of this locally ordered material, essential for understanding the structure-property relationships of these industrially important alloys.
