| Abstract: | Electron backscatter diffraction is used to study the microstructural evolution of cold‐spray aluminum coatings on Al2O3 substrates. The influence of powder purity and substrate heating on the kernel average misorientation and the distribution of low‐angle grain boundaries in as‐sprayed and annealed coatings are discussed in terms of dynamic recovery and dynamic recrystallization. |
