A novel technique, with which in situ TiB_2 particles and serpentine channels are introduced to prepare wrought aluminum alloy with higher strength, has been successfully applied to produce semi-solid 7075 alloy slurry. The effects of in situ TiB_2 particles and serpentine channels on the microstructure of the 7075 alloy including the grain growth behavior in the semi-solid state of the 7075 alloy were investigated. The experimental results showed that the in situ TiB_2 particles and serpentine channels are beneficial to increase the number of solidification nuclei and to promote uniform distribution of α-Al nuclei. As a result, the semi-solid 7075 alloy slurry with globular-like grains has been successfully produced.
