摘　　要：介绍了国内外在金属三维点阵结构制备方法的研究进展,及不同制备方法的特点,并进行了对比分析。提出了一种超塑成形/扩散连接工艺(SPF/DB)来制备金属三维点阵结构的方法,这种方法将点阵夹层结构看作三层或多层夹层结构,采用SPF/DB工艺方法在一个热循环中制备了金字塔型、四面体型、X型等典型的金属三维点阵结构,验证了工艺的可行性,为金属三维点阵结构的制备开辟了一条新的技术路径。对比分析了增材制造方法、塑性成形方法、SPF/DB等制备方法的特点和优点,对金属点阵结构技术的发展进行了展望。The research progress on fabrication methods of metal three dimensional lattice structure is introduced at home and abroad, as well as the characteristics of the methods. SPF/DB（Superplastic forming/Diffusion bonding） process is proposed to fabricate metal three dimensional lattice structure, which regards the lattice sandwich structure as three-layer or multi-layer hollow structure. Typical metal lattice structure including pyramid, tetrahedron and X-type are prepared by SPF/DB in a heat cycle, which validates the SPF/DB process. The characteristics and advantages of additive manufacturing, plastic forming, SPF/DB are compared and the advance of fabrication methods of metal three dimensional lattice structure is forecast.
