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: Industrial application, Near-net forming, Semi-solid processing, Theory innovation
