Abstract: Some new research development of semi-solid forming
technology in recent ten years is commented, which included rheology and
plastic deformation, non-dendritic mechanism of preparing billets (or
slurry) and some problems of industrial application. The authors think
that our country’s study on semi-solid technology is synchronous to that
of foreign country, but our industrial application is delayed, it is
important to strengthen research on preparation of billets, make
semi-solid technology develop with high efficiency, high quality and low
cost, strengthen the cooperation of university, research institute and
factory, organize some researchers to solve the bottleneck problems that
hinder technology’s application and introduce foreign technology and
equipments and let more manufacturers enter in this activity to promote
our country’s development in the semi-solid processing field.
Key words: Semi-solid processing Near-net forming Theory
innovation Industrial application
