| 中文摘要 | Pores, or voids, at oxide-alloy interfaces are commonly observed after high temperature oxidation when the alloy does not contain a reactive element. In order to under stand the pore-nucleation and growth processes, the density, size and depth of interfacial pores on Fe-40 at. %Al as a function of oxidation time at 1000degreesC were examined. Scanning-electron microscopy (SEM) and atomic force microscopy (AFM) were used to characterize the pores after removal of the surface Al2O3 scale. The nucleation of pores was most rapid during the initial stage of oxidation where cation-transported-alumina growth dominates. Pore growth involves widening as well as deepening, where the deepening rate is slower for larger pores. Growth is accomplished by aluminum evaporation after similar to20 min or by surface diffusion before that time. Pore shape within an alloy grain stays constant and is dictated by the balance of surface and interface energies. |
