extension of application of magnesium alloys in the more demanding components requires major development in processing technologies. It is well known that the semi-solid metal(SSM) processing... significance. In general, the semi-solid metal(SSM) processing is mainly composed of three main processes, such as production of semi-solid material with non-dendritic microstructure, partial......

; semi-solid slurry; solidification rate; microstructure 1 Introduction Semi-solid metal processing technology was ?rst proposed by SPENCER et al [1]. Compared with traditional casting and forging process, semi-solid forming has advantages such as lower processing temperature, smaller deformation resistance, less macro-segregation and solidi?cation shrinkage [2-4]. Various techniques of semi-solid......

Thixoforming is one branch of semi-solid processing of alloy, which forms alloys in the semi-solid state to near net shaped products... for preparing AZ91D magnesium alloy semi-solid billet. Furthermore, it is found that applying ECAE to strain induced step in SIMA is a good engineering application to semi-solid processing of magnesium alloy......
, proves SSM compressor wheels emerge as being significantly more durable than cast equivalents and approaching that of MFS impellers. Further challenges for semi-solid processing in manufacture... and reducing emission. The downside is that MFS is significantly more expensive than casting. Therefore, semi-solid moulding (SSM) processing is applied......
