Abstract:

A morphological transition from ellipsoidal Omega particles to cuboidal particles is reported to occur while isothermally aging in Ti-10V-2Fe-3Al. In light of this discovery, as well as others, the Beta to Omega reaction of Beta stabilized Ti alloys is discussed. An isothermal growth mechanism which couples minor compositional fluctuations and lattice displacement waves is proposed. Author
