Abstract
Microstructure of metastable cobalt-based alloys with 0.94, 1.4, 2.6 and 5.4 wt% iron, obtained by rapid quenching from the melt, was studied by X-ray diffraction. The as-quenched alloys of all concentrations show the fcc structure, which is present in the equilibrium diagram in the high-temperature region. The analysis of X-ray diffraction line profiles and line shifts of quenched alloys revealed that the residual strains and the stacking fault probabilities decreased with increasing concentration of iron. This may be explained with local polymorphic changes of f c c structure. Stacking fault energies, Vickers microhardness data and coercivity were measured, while residual stresses were calculated using both X-ray diffraction and magnetometric measurements.
