1、As the fracture surface of material is rugged, the region between reinforcement and matrix is prone to make cracks and diversions and to even produce bigger gaps, which indicates that the combined surface between reinforcement and matrix is vulnerable to reduce the flexural strength of material.
2、The mark of extracted grain crystal is apparent in the picture, which makes clear that the grain crystals are combined closely to improve the flexural strength of material greatly.
3、The fracture surface of material is relatively smooth. A large quantity of liquid phase gathers on the surface, and a certain number of holes begin to appear in the sample, thereby the density and flexural strengthen of material reduce further. |
