The role of ω in the precipitation of α in near-β Ti alloys

Abstract
To identify the conditions under which É· assists α formation in a near-β Ti alloy, we employed transmission electron microscopy and atom probe tomography to study α precipitation in alloys designed to contain two different types of É·. Coherent incommensurate embryonic É· formed upon isothermal ageing, does not directly assist α precipitation. When this incommensurate embryonic É· grows to a critical size, it transforms into commensurate isothermal É·, during which stress is thought to be the dominant factor. Regions of O enrichment at the semi-coherent isothermal É·/β interfaces are observed, which is thought to promote α formation.
