On annealed Ni-34.6 at % Al at 1523 K and effects of cooling rates

  • Tianyi Cheng


The microstructures and room temperature mechanical properties of melt spun Ni-34.6 at % Al annealed at 1523 K for 2 h and cooled at different rates were studied. The annealed microstructures and bend ductility were sensitive to the cooling rate. The distribution and relative content of γ precipitation were important factors for enhancement of bend ductility of the annealed ribbon. The best bend ductility of the annealed ribbon reached 7.6%, which was considerably better than the as-melt spun ribbon. The emission and transmission of dislocations from ductile γ′ into β to satisfy the need of deformation compatibility played a key role in the improvement of the ductility.
