Abstract

A hydrogen-induced microcrystalline-to-nanocrystalline transformation was observed in an Al 2.3Ti alloy, following hydrogen charging. The uncharged αAl was composed of small equiaxed grains. After cathodic charging, a very fine microstructure composed of nanocrystals formed on the previously equiaxed grains was observed. Transmission electron microscopy and X-ray diffraction analysis show that both the microcrystalline and the nanocrystalline phases coexist during the cathodic charging process. Results show that the microcrystalline-to-nanocrystalline transformation is partially reversible.
