Fracture at Elevated Temperature.

Abstract

Fracture at elevated temperature in dispersion strengthened alloys occurs by preferential nucleation and growth of voids at the inclusions present in the grain boundaries. It is shown how the stress-rupture life depends upon: stress, temperature, grain size, volume fraction of inclusions, size of inclusions and the strength of the inclusion-matrix interface.
