Phase transformation stress in titanium alloys in additive manufacturing

Abstract: Residual Stresses are a big challenge in 3D printing. They develop because the deposited material cools down, but it cannot shrink.One of the most widely used materials in 3D printing is the titanium alloy called "Ti64", which has a special material characteristics in terms of stress.Ti64 is very strong and can therefore develop very large stress without failing.When the material cools after the deposition, it shrinks due to thermal contraction, as any other metal. However, at 1000 degree the crystallographic structure changes (from beta to alpha). The low temperature crystal is much smaller, which further increases the residual stress significantly.We started to use a different titanium alloy (Ti5553), which does not undergo this phase transformation and we would like to investigate the unit cell volume of the crystals.
