A shock recovery experiment and post-shock mechanical measurements were conducted on high-purity Zr. Mechanical properties of the Zr samples before and after the shock loading are compared and discussed in terms of the substructure evolution during shock loading. Metastable [omega]-phase was found in the Zr sample following shock-loading to 7 GPa. A new orientation relationship between the [alpha] and [omega] phases was derived which does not agree with those previously reported in hydrostatic pressure experiments. A mechanism is proposed for the observed [alpha] [r arrow] [omega] transformation in Zr. [copyright] 1994 American Institute of Physics
