| Abstract Scope |
Shuffle transformation is a distinct class of displacive transformation, accomplished by the rearrangement of atom positions within the unit cell, with little or no pure strain of the lattice. For example, the beta to athermal omega phase transformation in the metastable beta titanium alloy is a prototype shuffle transformation. The hexagonal structured athermal omega phase is produced by the shuffle of every two of three adjacent {111} planes in the bcc lattice towards to the intermediate plane of the two, leaving the third plane unaltered. Recently, a novel shuffle transformation, beta to O' phase transformation, has been explored in the metastable beta titanium alloy for the first time using advanced electron microscopy. In this work, the mechanism of beta to O' phase transformation and the influence the solute concentration and temperature on the O' phase will be introduced. |
