Abstract:
Structure of an iodide zirconium single crystal prepared by zone melting has been studied by X-ray diffraction and optical and electron microscopy. It has been shown that the initial single crystal consists of macroscopic hcp packets, which are revealed by etching in crystal sections and differ in shape and dimensions (0.3-0.8 cm(2)). The orientation of each packet obeys the Burgers orientational relationships. Five different orientations of hcp packets of six possible variants have been found. The microstructure of each of such regions consists of a set of laths of the alpha phase of identical orientation separated by low-angle dislocation boundaries. The existence of structural heredity in the zirconium single crystal after a cycle of alpha ->beta -> I +/- transformations at the rate of heating and cooling on the order of 4-5 K/s has been confirmed. After quenching of a pseudo-single crystal of zirconium from a temperature of 960A degrees C in a 10\% NaCl solution, the packet structure of the alpha phase is retained, but the dimensions of the laths decrease severalfold.
