| Abstract Scope |
Some metastable β Ti alloys undergo a reversible phase transformation to a martensite, giving rise to a wide range of attractive properties with potential application across multiple industrial sectors. This transformation can be thermally or mechanically induced, however, large variability in the reported transformation parameters exists, independent of alloy composition. This variability can be linked to processing conditions which has recently been shown to influence the relative stability between the β and martensite phases. However, it remains unclear the extent to which this initial variability influences subsequent transformation behaviour.
This work uses a combination of in situ and ex situ characterisation techniques to understand the effect of this initial β phase stability on cyclic transformation behaviour, highlighting how the initial differences in phase stability only have a transient effect on mechanical response. This work gives important consequences for the design of new alloys suitable for use in cyclic loading regimes. |
