Tcherdyntsev, V V and Titova, V Yu and Kaloshkin, S D and Baldokhin, Yu V and Zagainov, A V and Rodin, A O (2011) Structure and magnetic properties of mechanically alloyed Fe3-xAlCrx powders. In: VI International Conference on Mechanochemistry and Mechanical Alloying (INCOME 2008), 1-4 December 2008, NML Jamshedpur, India.
Mixtures of elemental powders of Fe3-xAlCrx composition, where x ∈ (0.8 -1.2) were mechanically alloyed in the AGO-2U planetary ball mill. Obtained powders consist of particles with median size of 0.5-1.6 µm; increase in the Cr content results in the decrease in the size of particles. According to the X-ray data, all of the as-milled alloys possess a single-phase disordered b.c.c. structure. Increase in Cr content results in the decrease in the grain size of alloys, whereas the dependence of the lattice parameter on the chemical composition is not conclusive. Mössbauer spectra for most of the alloys shows that iron atoms in this alloys, in spite of the fact that only one phase was detected using the X-ray diffraction, exist both in ferromagnetic and non-ferromagnetic conditions.
