Abstract

The martensitic HCP-FCC transition in pure Co at TM approximately 700K exhibits premonitory effects found by purely elastic and by inelastic neutron scattering. Above T/TM approximately 0.95 preformed cubic nuclei start to grow considerably. At about the same temperature the elastic shear constant c44 decreases sharply. Approaching T M the entire TA branch corresponding to c44 goes down in energy. No pronounced soft mode behaviour, however, could be found.
