    Abstract
  • The effects of high pressure treatment on the compressive strength of aluminum bronze were investigated, based on the measurement of its compressive strength, the analysis of its phase composition, and the observation of its microstructure and fracture morphology by means of electronic universal testing machine, X-ray diffraction, optical microscope, transmission electron microscope (TEM), and scanning electron microscope (SEM). The results show that high pressure treatment is favorable to form fine-grained microstructures and can reduce the compressive strength of aluminum bronze, while the compressive strength of the aluminum bronze treated at 2 GPa and kept at 600 ℃ for 2 min is increased about by 34%, compared with the as-cast alloy.
