Abstract Scope |
A combination of FEM models and MIPAR deep learning algorithms was used to predict and determine prior Beta grain sizes in super-transus Ti-6Al-4V and needle growth in TiB - Ti MMCs. Electronically insulating boron nitride was used to coat graphite foil and inserted between the sample region and graphite moulds to direct the current flow generating spatially targeted joule heating. A range of extreme thermal gradients were created with no other alterations to the sintering recipe and their impact determined through imaging and physical testing.
The utility and flexibility of the Current Control techniques is also demonstrated through the creation of samples of greater radial and axial dimensions with the reduction of these thermal gradients. This is a regular challenge for the production of components at scale and solving it would allow for more homogenous billet production for industrial applications through FAST processing. |
