Experimental evidence was presented which showed that deformation could induce the transformation of small Cu-rich precipitates from the coherent body-centered cubic phase to the 9R phase in aged binary Fe-Cu alloys. This was in broad agreement with molecular dynamics simulations of the interaction of dislocations with Cu precipitates carried out by Bacon et alia.
