Kinetics of mechanically activated disproportionation of NdFeB alloy during reactive milling in hydrogen: Experimental studies, mechanism and modelling

Disproportionation kinetics curves of Nd16Fe76B8 alloy by reactive milling under various conditions are plotted by using the proposed kinetic equation y = 1 − exp[−(λk)t/Ea], with the experimental data illustrated for comparison as presented below, and good agreement verifies the model's rationality. Such work can help to predict the disproportionation kinetics and optimize the process parameters for production practice. Comparison of theoretical kinetics curves with experimental data under various milling conditions.
