Mechanically induced phase transformations of the sigma phase of nanograined an...
Costa, B. F. O.; Caër, G. Le; Loureiro, J. M.; Amaral, V. S.A coarse-grained tetragonal sigma phase [sigma]-Fe0.54Cr0.46, prepared from an as-cast alloy, and a nanocrystalline [sigma]-Fe0.52Cr0.48 phase were ball-milled in argon in a Fritsch P0 ball-mill at different vibration amplitudes. X-ray diffraction evidences solely a gradual transformation of the sigma phases into bcc phases. Room-temperature Mössbauer spectroscopy shows further the presence of a non-magnetic ph...
