Sep 15 2015018332An increasing amount of Fe 3 O 4 is detected when the powder used for the consolidation has spent a longer time in the planetary ball mill The presence of SrO is virtually impossible to detect in the Xray diffractograms as all the SrO peaks overlap with the SrFe 12 O 19 and Fe 3 O 4 phases.
The materials were prepared in a planetary ball mill using a ballstopowder mass ratio of 151 and pure 9995 at Fe Mn and Al powders for times up to 19 h The Xrays diffraction XRD spectra show the coexistence of three phases at short milling times For milling times over 6 h only the FeMnAl ternary alloy BCC phase is observed.
The obtained results showed that only the powder ballmilled for 120 hours yielded a near porefree material after consolidation by cold pressing and pressureless sintering at 900176C Assuch it could have a potential to be used in production of diamondimpregnated wire saw beads.
