Abstract
This thesis presents a study of some aspects of the powder metallurgy of titanium. With such a reactive metal it is impossible to avoid oxidation and particular emphasis is placed on how oxide films may affect both pressing and sintering. A sensitive, electrical resistance method and dilatometry were chosen to monitor these processes and initial work was carried out on high purity powder. This was produced by the hydride- dehydride process after establishing the conditions required to produce a fine powder which could readily be oxidised. The results obtained from sintering experiments using this material were not suitable for quantitative analysis so a mathematical model was devised to relate resistance change to the processes taking place during the sintering of spherical particles. This model was then tested using simple arrangements of spherical particles.
