| Abstract: | The paper research effects of heat treatment on microstructure and dezincification corrosion properties of C46500 brass. The results confirm that the extrusion microstructure has a and fl phases, the β-phase transform to a-phase by the high temperature annealing treatment, the solubility reaches extremes at 480 ℃. And the network microstructure of β organized changes to equiaxed organization by high temperature annealing the material of C46500 brass has good anti- dezincification property after 480 ℃ ＋ 6 h annealing treatment. |
