Title: METHOD FOR OBTAINING A BETA PHASE IN PURE TRANSITION METALS OF GROUP IV OF THE PERIODIC SYSTEM
Abstract:
The present invention comprises a new method for controlled manufacture of the beta phase stable at ambient temperature and pressure of pure transition metals of group IV of the periodic system. The process which takes place at ambient temperature comprises, firstly, application of pressure to the sample and, subsequently, while maintaining this pressure, exerting shearing deformation to the same. The pressures and temperatures required are much lower than those necessary for obtaining the beta phase of transition metals of group IV through other available techniques, such as the diamond anvil cell.
