Comparison of SiC dissolution rate using simulated cells with stoichiometric lattice and an incoherent grain boundary. (a) and (b) compare the dissolution rate of Si species in GB and stoichiometric regions. (a) and (b) displays the dissolved Si atom for the Si-rich and C-rich GB, respectively62 2022|AFC ACCOMPLISHMENTS'
