| 中文摘要: |
| 半固态成形技术充分利用金属材料在半固态温度区间特殊的微观组织和成形性能，能够在较低的成形载荷下实现复杂构件的高效近净成形，该技术的应用对于提高金属材料的质量利用率和性能利用率、延长模具寿命、节能减排等方面具有重要的作用。主要介绍了半固态成形技术的历史沿革、半固态成形技术的分类、半固态金属坯料浆料的制备工艺、有色金属材料和钢铁材料的半固态成形技术开发以及应用情况，最后提出了半固态成形技术所面临的挑战和机遇。 |
| 英文摘要: |
| On the basis of the microstructure and forming properties of metals in semisolid state, semisolid forming could be employed to realize the net shape forming of products with complex geometric shape effectively. The application of semisolid forming can increase the material quality utilization and properties utilization, prolong the lives of dies, realize energy conservation. This manuscript mainly introduces the historical evolution of semisolid forming, classification of semisolid forming, manufacturing methods of semisolid metal slurries, technology development of semisolid forming of non-ferrous metals and ferrous metals, and points out the opportunities and challenges of semisolid forming. |
