摘要
Fine-grained silicon carbide with a continuous second-phase grain-boundary film was crept under compressive loading at 1600 degree C. The shape of the resultant grain-boundary cavities was characterized using small-angle neutron scattering. During the early stages of creep the cavities grew more rapidly in the plane of the grain boundary. During the latter stages of creep the cavities grew more rapidly perpendicular to the grain-bondary plane.
