Abstract： With its high design freedom andrapid prototyping capabilities，additive manufacturing （AM）ofers significant advantages inmanufacturing criticalcomponents withcomplex geometries for theaerospaceanddefense industries.Ti-6Al-4V alloy，leveragingitsexceptionalcombinationoflowdensity，ighspecificstrength，andcrepresistance，areextensively employed incritical structures that are frequentlysubjected to impact loading inaerospace and defense systems.A thorough understandingof themechanical propertiesandunderlying mechanismsof theaditivelymanufacturedTi-6Al-4Vallyunder staticanddynamic loading iscrucial forenhancingtheserviceperformanceof thesecomponents.This paper systematically reviews and summarizes the latest advancements in the mechanical response of AMTi-6Al-4Vtitanium aloys.Firstly，a brief overview of the classification and working principles of typical metal aditive manufacturing （AM）technologies is provided. Subsequently，research eforts on thequasi-static tensile and dynamic compressive propertiesof additively manufactured Ti-6Al-4V titanium alloyaresystematicallyreviewed，followed byacomparativeanalysisof itsmechanical performance against cast and forged Ti-6Al-4Vcomponents.Furthermore，the mechanismsof corelation between the microstructure and mechanical behaviorsoftypical metaladitive manufactured itanium alloys.Additionally，thecommonlyusedpost-processing techniques to mitigate the anisotropic mechanical response of AM Ti-6Al-4V alloy under static loading are summarizes.

根据美国材料与试验协会（American Society for Testing and Materials，ASTM）对增材制造（additivemanufacturing，AM）的定义——与减材制造相反，依据3D模型数据，通过将材料一层一层地堆叠以制造所需部件，增材制造也被称为3D打印、叠层制造和自由成形制造等[1]。（剩余45490字）
