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。

关 键 词:钛合金,三维点阵,制备方法,超塑成形/扩散连接

Abstract:In this paper, the fabrication method of metal three dimensional lattice structure are classified, the characters of every method are discussed and compared. According as the characters of SPF/DB(Superplastic forming/Diffusion bonding) process, it is introduced into fabricating three dimensional lattice structure, the lattice sandwich structure is looked as three-layer or multi-layer hollow structure, three type lattice sandwich structures are fabricated, it is verified that the feasibility of SPF/DB process is validated, this new method will promote the development of metal three dimensional lattice structure.The characteristics and advantages of additive manufacturing method, plastic forming methods ,SPF/DB method are compared, it is convinced that the SPF/DB process is a suitable method to produced large size, complex shape of the sandwich structure, so in the future, lattice sandwich structure fabricated through SPF/DB process will has good prospects in hypersonic aircraft and its high thrust to weight ratio engine .
Keywords:titanium alloy  three dimensional lattice structure  fabrication method  SPF/DB
