WebThe new alloy transformed from the BCC to hexagonal closed-packed (HCP) phase initially. With increasing load the HCP phase was gradually converted into face-centred cubic (FCC); the resultant HCP/FCC nanolaminates enhanced plasticity via strain partitioning. Under higher loads, the FCC phase became dominant, giving rise to deformation twinning.
