Whereas, model-free iso-conversional methods are used to determine the kinetic-triplets during the non-isothermal oxidation stage, power-law dependent kinetic model is considered during the entire oxidation process to calculate the reaction order, rate constant and the apparent-activation energy. A distinctly different oxide growth kinetics, with strong dependency on the initial particle size(s) and the alloy composition-induced oxide microstructure is seen here.falseKinetic-triplets | Kinetics | Oxidation | Powder | Sm2(Co, Fe, Cu, Zr)17Article1 May 20241111932arJournal2WOS:001208316500001
