It was emphasized on basic theories, such as formation of globular grains, theology, high pressure solidification and plastic deformation and applications, such as material design, preparation of semi-solid billets （slurries）, thixoforming and application status, which are based on the advantage of semi-solid processing. The results show that the gap of SSP between world level and China exists, especially in application technologies, including market recognition, application fields exploiting, developing of billets （slurries） preparation technologies with low cost and special equipments. The prospect of semi-solid forming development path in China is presented. And we hope that application of SSP has great new breakthrough and development and China wilt be changed from a large metal processing country to a powerful metal processing country.展开更多
