A coupled theory for deformation and phase transformation due to CMAS infiltration and corrosion of thermal barrier coatings

•A mechanism-based phase field approach is proposed for the process of phase transition happening in corroded TBCs.•The infiltration of CMAS and the extension of monoclinic phase are captured by both model and experiment quantificationally.•Out-plane tensile stress σyy accumulates in the interface b...
