Abstract
Binary Ti alloys bearing beta eutectoid stabilisers (i.e. Cu and Mn) were produced by powder blending followed by cold pressing and vacuum sintering as this is identified as an alternative cost-effective manufacturing method to lower the cost of Ti alloys. The sintered Ti-Cu and Ti-Mn alloys were subsequently heat treated via a solution treatment in the beta field plus aging. The aim is to investigate a cheap and efficient method to change and tailor the mechanical behaviour via microstructural control. Heat treating the binary Ti-Cu and Ti-Mn alloys slightly affects their relative density and significantly changes the nature of the phases composing each material. This includes the transformation of the typical lamellar structure into lamellar hypo-eutectoid structures as well as the formation of metastable phases. The response to the heat treatment and the phases formed are clearly influenced by the chemistry of the beta eutectoid bearing binary Ti alloys. Performance comparable to those of thermomechanically hot forged alloys are nonetheless achieved via a simple heat treatment procedure.
