| Abstract: | The application of the Fe-Cu-C alloys in gelcasting was discussed. Effects of the solid volume fraction and granularity on the drying rate and the shrinkage ratio were studied . Effects of the granularity on the rtiaximal solid volume fraction were investigated. It is suggested that the process can obtain uniform structure and complex shapes of Fe-Cu-C alloys, the products have relative density of 90%, tensile strength of 365MPa and flexural strength of 1080MPa were prepared by gelcasting. |
