Here, we apply a correlative tomography-based mass balance framework to Cr$_2$AlC, a coating candidate for accident tolerant nuclear fuel claddings and turbine blades, and show that decomposition and pore evolution during oxidation, quantified by integrating volumetric, structural and compositional data, are strongly governed by grain morphology. The oxidation of sputtered Cr$_2$AlC coatings with equiaxed and columnar grain morphologies was analyzed. While Cr$_7$C$_3$ formed in both coating mor","authors_text":"Devi Janani Ramesh, Jochen M.
