Introduction
The DST / NRF Centre of Excellence in Strong Materials (CoE-SM) is a major South African Research Network hosted by the University of the Witwatersrand, in partnership with the Nelson Mandela Metropolitan University, the Universities of Johannesburg, KwaZulu-Natal and Limpopo, the Council for Minerals Technology (MINTEK) and the Nuclear Energy Corporation of South Africa (NECSA). There are more than 30 researchers over 80 postgraduate students active in the Centre from a number of disciplines including physics, chemistry, ceramics, metallurgy, chemical and mechanical engineering.
Strong materials are those that retain their distinctive scientific and applied properties under extreme conditions and have established or potential commercial applications.
Extreme conditions include some or all of the following:
High stress; High wear conditions; Extreme temperatures (high and/or low); Harsh chemical or corrosive environments; Strong fluxes of damaging radiation.
Distinctive properties retained would typically include one or more of the following:
Hardness and toughness; High mechanical strength and stiffness; wear, corrosion or radiation resistance
Research programmes of the Centre involve the prediction, design, synthesis, evaluation, development and exploitation of strong materials.
