Abstract
The formation of the gamma hydride phase through a shear transformation has been studied in a Zr-20%Nb alloy and in iodide pure zirconium. The crystallography of the beta to gamma and the alpha to gamma transformations has been discussed. A possible mechanism for the alpha to gamma reaction, involving the intermediate formation of the beta phase, has been suggested.
