Review on criteria for assessing the processability of semisolid alloys

Abstract

In recent years, the semisolid processing has received extensive interest because of its noticeable advantages, and a series of criteria have been proposed to assess the processability of semisolid alloys. The aim of this work is to conduct a focused review on the criteria for evaluating the processability of semisolid alloys. It was found that the temperature sensitivity criterion is more commonly adopted, while the time sensitivity criterion has demonstrated a greater adaptability and the enthalpy sensitivity criterion seems to be more reasonable. Despite no general consensus, these criteria actually provide multi-angle evaluation methods for effectively assessing the suitability of semisolid metal (SSM) processing. In the future, the detailed criteria for assessing the semisolid processability of specific alloys need to be further explored, and it is particularly worth extending the evaluation criteria to Mg alloys due to their excellent lightweight effect and potential application, which is expected to attract wide attention of researchers in the semisolid processing field.
