Interfacial morphology of low-voltage anodic aluminium oxide

Neutron and X-ray reflectivity, as well as small-angle scattering, are used to probe the in-plane and surface-normal structure of anodized aluminium. A new low-voltage anodization protocol gives smooth anodic films on aluminium, suitable for investigation by neutron and X-ray reflectivity.

Multiple twinning in pure hexagonal close-packed titanium

A study of multiple twins in commercial pure titanium evidenced the influence of twinning order on the multiple twin variant, the role of the normalized Schmid factor in the twin variant selection, and the critical condition of twinning being activated by another twin in a neighbouring grain.
