| Abstract: | The molten metal of alloy under the action of electromagnetic field was studied for the rheoforming technology, microstructure and performance of the alloy ZL201 in semi-solid state in AC electromagnetic field. The results showed that the semi-solid alloy can be molded up with smooth surface, precise size, compact microstructure and without pores and inclusions under the action of the 18 A/50 Hz electromagnetic field if the temperature of melt is 650 ± 1°C and that of mold is 510 ± 1°C. The hardness of the molded specimen is up to 108 HV5, 1.5 times as high as that of the one being not rheoformed. The results will lay down a foundation for the application of rheoforming technology to semi-solid aluminum alloys. |
| Keywords: | ZL201 alloy electromagnetic rheoforming microstructure hardness |
