{beta} metastable alloys have, potentially, better cold formability and age-hardening response than {alpha}-{beta} titanium alloys. In the {beta} metastable alloys, the Ms temperature is below room temperature and the {beta} phase can be retained in a metastable state. {beta}-Cez is an alloy initially developed for turbine compressor applications. Most of the research on this alloy has concentrated on its structural stability, its high temperature deformation microstructures, its phase transformation kinetics and the structure/mechanical properties relationships. Little information is however available concerning the room temperature deformation mechanisms that actually control the mechanical properties of the alloy. Production of wires or thin sheets of the {beta}-Cez alloy that are obtained by cold deformation and subsequent heat treatments is currently under development. The optimization of such manufacturing processes has made it necessary to examine more precisely the deformation mechanisms of {beta} rich microstructures in this alloy. The aim of this work was therefore to clarify which are the deformation mechanisms and to what extent they affect the mechanical properties.
