| Abstract: | The microstructures and properties of rheo-diecasting ZL201 aluminum alloy have been investigated.The preparation of semi-solid metal,rheo-diecasting,solid solution and aging treatment have been investigated as well.The results show that the semi-solid metal with uniform,fine,near-spherical microstructures and non-dendrite crystal can be obtained while the alternate electromagnetic field exerts on nearby liquidus temperature line;the die cast products prepared by semi-solid metal possess isometric crystal or rosette crystal structure;the tensile strength of ZL201 aluminum alloy can be 253 N/mm2,elongation can be 7% after T5 heat treatment;the microstructures and mechanical properties of rheo-diecasting parts are superior to those of thixo-diecasting part. |
