Abstrakt: An investigation has been made of the various phase transformations which occur when dilute Ti-Mo (0.5 and 1.0 wt% Mo) alloys are cooled from theß phase field and are subsequently tempered in thea +ß phase field. The morphology of the decomposition products varied with cooling rate and can be correlated with the competition between the formation ofa' by martensitic and by diffusional processes. On isothermal transformation below theMs, or upon tempering,ß phase precipitates grow heterogeneously from the supersaturateda' plates formed by shear. The precipitate habit plane is irrational and corresponds to the {334}ß plane.
