摘要: Abstract Dual-phase amorphous-nanocrystalline A l 0.74 M o 0.26 alloy film was fabricated by annealing-induced crystallization (AIC) in precursor of amorphous at 550 °C. The precipitated 3 nano-grains with average size of ~5 nm uniformly dispersed Al-Mo matrix. Additionally, the dual-phase structure maintained even when annealing process performed above temperature. unexpected thermal stability resulted from effect diffusion field impingement. Ham model employed to quantitatively describe kinetic stabilization mechanism film. Furthermore, prepared benefited combined and nanocrystalline phase, which exhibited outstanding mechanical properties elastic modulus hardness as high 240 17 GPa, respectively. Also, had extraordinary corrosion resistance very positive potential, low current stable passive state.
