A Study of the Interfacial Stability of Ti/Al2O3, Ti3Al/Al2O3 and TiAl/Al2O3 Composite Materials
This thesis is a study of the interfacial stability of the Ti-Base metal matrix composites Ti/Al2O3, Ti3Al/Al2O3 and TiAl/Al2O3. Interfacial stability is discussed in view of the importance of thermodynamics and kinetics as the primary considerations which govern the type of stability observed. From a thermodynamics approach, the application of phase equilibrium diagrams is essential in the design of composite systems. A classification system, with reference to phase equilibrium, is used to describe the type of interfacial stability observed for the composites studied. In addition, electron-probe microanalysis, atom-probe field ion microscopy and X-ray diffraction results are used to establish Ti-Al-O phase relations for the temperature range 900-to-1250 deg C. The kinetics of interfacial stability is discussed with particular attention given to the kinetic considerations; diffusion path, phase formation sequence, steady-state layer growth and interface morphology. Kinetic results in the form of parabolic growth constants and calculated interdiffusion coefficients are presented.

"In 1972 Craig Williamson, a big, burly, bearded man, walked onto Wits University and registered as a student. He joined the National Union of South African Students (Nusas), and was on the frontline in the war against apartheid. At one march he was beaten up, arrested and spent a year on trial. Williamson rose up through the student movement's ranks to become the Nusas vice president. After being harassed by security police and having his passport seized, he decided to flee the country to continue his activism with the International University Exchange Fund (IUEF), an anti-apartheid organisation in exile. He was eventually appointed the Fund's deputy director. As the IUEF's money man, Willi...

Change the Story, Change the Future
We humans live by stories, says David Korten, and the stories that now govern our society set us on a path to certain self-destruction. In this profound new book, Korten shares the results of his search for a story that reflects the fullness of human knowledge and understanding and provides a guide to action adequate to the needs of our time. Korten calls our current story Sacred Money and Markets. Money, it tells us, is the measure of all worth and the source of all happiness. Earth is simply a source of raw materials. Inequality and environmental destruction are unfortunate but unavoidable. Although many recognize that this story promotes bad ethics, bad science, and bad economics, it will...
