Abstract

Solidification conditions of a 0.64 cm × 2.5 cm × 15.2 cm slab and a 1.3 cm ɸ × 15.2 cm bar were simulated for two NiAl alloys. Simulation results were correlated with experimental inspection results to establish a relationship between dendrite arm spacing and local solidification time. The results were also used to construct a defects map for NiAl single crystal castings. Results have been compared to a similar model for single crystal nickel-base superalloys.
