Abstract
The influence of heating rate on the thermal strain induced fracture of flat cylindrical rings is investigated. The heating rate of the inner surface was maintained at 4.6 and 450°C/min up to 1300°C. The temperature at various locations and the diametrical displacement were monitored during heat up and the temperature gradient at fracture recorded. Three grades of Mg-PSZ specifically heat treated or fabricated for thermal shock resistance were investigated. Apart from the critical temperature gradients the temperature dependence of the stress-strain behaviour and R-curve behaviour were measured. The latter results are qualitatively related with the thermal shock observations.
