Overview for Semisolid Metals Forming and Its Applications

This text has carried on brief summing-up to existing semisolid process technology, the key technology question and developing direction have been discussed and analyzed. The craft principle of semisolid process, the methods of thick liquid material and forming craft have illuminated and summarized, and its technology predominance and application have been expatiated; the semisolid forming is a process technology that it is close to take shape, it possesses non-dendritic crystal structure and thixotropic performance, so it is advantaged to environmental protection and sustainable development. It will have wide development and application prospect in such most advanced fields as the automobile, computer, communication, aviation, spaceflight and national defense etc.
