We used mechanical alloying with a Spex 8000 mixer/mill to synthesize a series of Fe100–xNix alloys from x=0 to x=49 The Spex mill was modified so that it could also operate at a reduced milling intensity and we compared the alloys synthesized after long times with the normal and reduced milling intensities X-ray diffractometry and Mss spectrometry were used to measure the volume
