Project Description

Project Overview:  A significant portion of high temperature materials are Nickel (Ni) based.  Long term oxidation in these systems has been thoroughly studied, however often neglecting the microstructure effects (ie. grain boundaries, grain orientation).  Additionally, few studies have considered the native oxide growth dependence on orientation as it relates to growth direction.   This project will examine early oxidation in Ni-Al alloys to determine the orientation dependency of the oxide growth.  Ni-Al samples will be pulse oxidized at short intervals (30-120s).  Samples will be mapped before/ after and SEM will be utilized to count nucleation sites and determine oxide growth direction.
