10257 fritsch ball mill p7 premium
Fe 80 Ni 20 was prepared by mechanical synthesis using a Fritsch Pulverisette Premium (P7) planetary ball mill at 400 RPM. The alloying process was monitored by measuring the magnetic properties of 14 subsamples taken at different milling times (12160 min) as well as structural modifications using powder Xray diffraction and highresolution imaging.
