Phase Transformations in Fe-Mn Alloys Induced by Ball Milling
- 1. Universidad Nacional de La Plata C.C. No. 67, Departamento de Fisica, IFLP, Facultad de Ciencias Exactas (Argentina)
Description
We have studied the dependence on the milling time of the amounts of metastable fcc and hcp phases produced by ball milling on Fe-13.7 wt% Mn alloys by Moessbauer spectroscopy and X-ray diffraction. The relative proportions of γ-Fe(Mn) fcc and ε-Fe(Mn) hcp increase with milling times up to 9 h and decline afterwards. A random solid solution of Mn in the α-Fe matrix is found for milling times up to 15 h. Mn segregation is observed after 25 h. The evolution of the relative percentages suggests that ball milling brings about processes that on the one hand induce the fcc/hcp martensitic transformation, and on the other favour transformations towards the phases dictated by the thermodynamic phase diagram.
