摘要: Abstract Stress–strain curves in compression were obtained as a function of temperature for both the disordered and fully ordered FeCo–B2 type superlattice only. Supplementary observations made surface slip markings after various strains, well dislocation configurations existing these using transmission electron microscopy techniques. It has been found that deformation process occurring alloys is similar at all strains. Furthermore, flow stress strongly dependent on nearly independent strain. The profuse stepped lines observed specimens suggests thermally activated cross-slip controlling mode alloys. alloys, other hand, show three distinct stages to those face-centred cubic metals Stage I On II incre...
