Experimental and molecular dynamics simulation analysis of LaCrO3 precipitation in chromia scales Original Research Article

Experimental characterization of grain and grain boundaries of chromia scales upon addition of La has been carried out with a variety of techniques. The effect of lanthanum addition on the high temperature oxidation is explained based on simulations suggested by the experimental results. The grain boundary precipitation mechanism of perovskite phases suggested by our simulations is through the extraction of Cr atoms from the oxide scale.
