Abstract：

The microstructure and fracture reason for high strength aluminum-bronze alloy forging were analyzed using SEM.Through macrofractgraphic analysis and microstructure observation,the angle of 45° fracture and some crack areas were found in the alloys.The analysis results show that the intergranular fracture for high strength aluminum bronze alloy forging is due to the deformation stress exceeding the tensile strength and the K phase of the alloys becoming the source of fracture.
