The article determines the crystallography of a new metastable phase in Zr-N alloy. Selected-area and convergent-beam electron diffraction were used to determine the lattice, point and space groups of the metastable phase. This phase is body-centered tetragonal with a space-group symmetry of I4/mmm. The thinned specimen was examined in transmission electron microscope at 200 kV. The specimen was tilted along different Kikuchi bands to reach several low-index zone axes and the corresponding selected-area diffraction patterns were then recorded.
