摘　　要：铸造可以成形形状复杂的零件,但铸件的力学性能普遍较低;锻造可以成形力学性能较高的零件,但锻件的形状复杂度受到很大的限制。铸锻复合成形技术将铸造和锻造相结合,取长补短,可成形高性能复杂形状零部件。介绍了几种典型铸锻复合成形工艺,包括铸锻联合工艺、双重挤压铸造、铸挤锻复合工艺、压铸锻造双控技术、铸锻一体化成形技术等。重点介绍了铸锻一体化成形技术的研究进展,并对铸锻复合成形技术的前景进行了展望。Complex parts can be fabricated by casting,but the mechanical properties are usually low.High mechanical properties parts can be prepared by forging,but complex shape is very difficult to be obtained.Complex parts possessed high mechanical properties are easily prepared by casting and forging combination forming technology due to both casting process and forging process are combined.Several typical casting and forging combination forming technology,such as casting/forging process,dual squeeze casting technology,combined forming of extrusion-die forging,die casting and forging process are introduced.The casting-forging integrated forming technology is emphasis introduced and the future development of casting and forging combination forming technology is proposed.
