Abstract:Semisolid metal forming as a new nearnet shape technology in 21 century generally attracts people's attention. In order to promote its application in our country, the technology is analyzed and discussed from theoretical research, billet making, reheating, forming process, the newestdevelopment and trend of overseas application. Potential application prospect is pointed out about semisolid forming technology in automobile, electron and army industry. It is also clarified which countermeasure should be taken.
Key words: semisolid forming; nearnet shape; research and application
