| Abstract | Engineering alloys of heat resistance often generate pores at the scale/alloy interface during high temperature oxidation. The accumulation and growth of those pores greatly weaken scale adhesion. The purpose of this study is to observe pore development in Fe-40%Al (atomic fraction) and measure the change in pore volume with oxidation time. Experimental results are then compared to a theoretical calculation where all vacancies are allowed to condense as voids. After removing the oxide scales formed after various times of oxidation at 1000 degreesC in oxygen, the alloy surface was analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM) to determine the size and depth of interfacial pores. Results are discussed in light of possible mechanisms involved in pore formation at scale/alloy interfaces. |
