Abstract

The transformation on ageing Co-3 wt% Ti-1 wt% Fe and Co-3 wt% Ti-2 wt% Fe alloys has been followed by transmission electron microscopy and diffraction to establish that the solid solutions undergo spinodal decomposition at 823 and 973 K. The microstructural evolution has been correlated with the observed variations in hardness and yield strength. The coarsening of the modulations on ageing is seen to follow λ303=Kt kinetic law. After long periods of ageing a discontinuous coarsening process sets in.
