Abstract

This manuscript discusses the morphological instability observed when multilayered samples with alternating layers of γ-Ni(Al)/γ¹-Ni ₃Al are exposed to 800 degrees}C for approximately 100 h. Samples with 20 nm / 20 nm or 120nm/120nm layer thickness and <001> ir <111> crystal orientation and layer thickness. Corresponding modeling suggests that the stability of this system is sensitive to fluctuations in the volume fraction of the two phases, the aspect ratio of columnar grains in the layers, and whether coherent or semi-coherent interfaces are present.
