3 Terms and definitions

The following terms and definitions defined in GB/T 5611 apply to this document. 3.1 Semisolidrheologicalslurry The metal melt in the solidification process is processed by applying physical or chemical technical means to obtain a uniform metal melt. A solid-liquid mixture in which a certain proportion of non-dendritic primary solid phases (mainly spherulites or near spherulites) are suspended. 3.2 Rheological diecasting forming The semi-solid rheological slurry is transferred to the die-casting forming equipment, and the forming method of the part is obtained by one-time processing. 3.3 Solid fraction solidfraction The percentage of the mass of the solid phase in the semi-solid slurry to the mass of the slurry. Note. The solid phase fraction specified in this document is the solid phase fraction under equilibrium solidification conditions corresponding to the temperature of the semi-solid slurry. This solid phase fraction is not the actual solid phase Fraction. 3.4 Low solid phase semi-solid rheological slurry lowsolidfractionsemisolidslurry It can flow naturally without forming a semi-solid rheological slurry with a fixed shape. ......
