Project Images

Figure 1. The 2Al-34Ta-36Ir crystal structure model used in one of our simulations.
 The gray balls are Al atoms, blue balls are Ta atoms, and yellow balls are Ir atoms.
The two Ta atoms are substituted by two Al atoms.

after thermal gradient thermal cycling tests. Failure is mainly
caused by the spallation at the edges.
