CFD models created for blown-powder systems

  • March 28, 2016

During MMTECH, the complete process for additively-manufactured y-Tial will be modelled. Strathclyde have created a model to simulate powder flow as it is ejected from the nozzle during laser metal deposition has been created and allows substrate rebounds to be considered. The CFD model is a general analysis of powder dynamics and is essential for modelling subsequent processes suc...

Phase field models of γ-TiAl completed

  • June 15, 2016

A phase field model was completed to determine the microstructure evolution of gamma-titanium aluminides. The CALPHAD (CALculation of Phase Diagrams, left) method was first used to find the free energy of the individual phases of the material at different temperatures and then used in phase field modelling to predict the phase transformation at high cooling rates. The microstructure will ...

First γTiAl parts built

  • August 15, 2016

The first test parts made from γTiAl have been produced on the Optomec machine at the AMRC using powders from MBN. The next step is to carry out a number of builds with different parameters to see which settings produce dense, crack-free parts.
