Includes bibliographical references (leaves 121-125). === The Pt₈V ordering transformation in Pt 11 qt.% V alloys has been studied. The study included determining the thermodynamic stability of Pt₈V, the kinetics of Pt₈V ordering transformation and the strengthening due to the presence of the ordered phase. Transmission electron microscopy, using election diffraction and dark and bright field imaging, and X-ray diffraction were used for structural characterisation. Electrical resistivty was used to investigate the kinetics of Pt₈V ordered phase. Microhardness measurements were used to investigate the Pt₈V ordered phase and its effects on hardness.
