Analysis of structure and magnetic properties of nanocrystalline milled alloys

Fe-20% Ni alloys were prepared using a planetary ball mill P4 vario ball mill from Fritsch (with different milling conditions (Ω/ω), Ω and ω being the disc and the vial rotation speeds, respectively). An artificial neural network (ANN) methodology was applied to rely the powder milling process parameters (Ω/ω) to the structure and magnetic properties of the Fe-20% alloys. An optimization procedure based on ANN training and testing steps was developed to predict structure and magnetic properties over a large range of process parameters. The following features have been anticipated:
