| Popis: | X-ray diffraction results indicate that in the VFe alloy, the body-centered-cubic disordered structure can be almost completely retained by quenching from 1250°C. On annealing at 600°C, the disordered body-centered-cubic structure transforms into a CsCl-type ordered structure before practically any of the stable σ phase is formed. The increasing stability of the CsCl-type ordered structure from CrFe to VFe to TiFe indicates that the A-B bond increases in strength, as compared with the A-A and B-B bonds. This is accompanied by increasing brittleness, increasing lattice contraction, and the disappearance of ferromagnetism. It is probable that the increasingly strong A-B bond results from a quasi-ionic bond component due to electron transfer. |
