Abstract

Effect of heating treatment on microstructure and mechanical properties of a novel high aluminum bronze which was prepared by alloying method were investigated by XRD （X-ray diffraction）

SEM （scanning electron microscope） and HRS-150 Rockwell hardness tester

and the optimized parameters for solution-aging treatment were presented. The results show that the as-cast microstructure of alloy is composed mainly of α

β ’

γ2 and k phases. The hardness

tensile strength and elongation of the alloy prepared reach 42.6HRC

890 MPa and 9.84%

respectively

after 950 ℃×2 h solution（quenching in oil）+550℃×4h aging（cooling in air）

exhibiting acceptable comprehensive mechanical properties.
