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 TM the entire TA branch corresponding to c44 goes down in energy. No pronounced soft mode behaviour, however, could be found.Keywords
