Description
The driving force for nitrogen segregation was less than that for oxygen over the temperatures 1873-2233K. Increasing the bulk concentration of nitrogen increased the degree of oxygen segregation, whilst having no significant effect on the nitrogen segregation. The intergranular fracture stress and fracture energy decreased with increasing segregation levels of oxygen and nitrogen. However the fracture behaviour depended not solely on the degree of grain boundary segregation but also on the grain boundary geometry. Larger fracture energy values were obtained for the higher Coincident Lattice Site Index Σ-boundary. (orig.)
