摘要

研究了选择性激光熔化AlSi10Mg合金粉末板对接头搅拌摩擦焊接的工艺特点。AlSi10Mg合金板材是通过选择性激光熔化生长在90°角的构建平台。选择激光熔化生长的板材焊接接头的极限抗拉强度为274 ~ 306 MPa，板材弯曲角度为69°~ 85°。焊接接头沿混合区金属发生断裂。在母材微观结构中发现了以下两种类型的孔隙：沿可见熔浴边界的扁平孔隙和球形孔隙。混合区金属未发现孔隙。

Friction Stir Welding of the AlSi10Mg Aluminum Alloy Produced by Selective Laser Melting

The technological features of friction stir welding of the butt joints of AlSi10Mg alloy powder plates produced by selective laser melting are investigated. The AlSi10Mg alloy plates are grown by selective laser melting at an angle of 90° to a build platform. The ultimate tensile strength of the welded joints of the plates grown by selective laser melting is 274–306 MPa, and the bending angle of the plates is 69°–85°. The fracture of the welded joints occurs along the mixing zone metal. The following two types of porosity are found in the microstructure of the base metal: flattened pores along the boundary of visible melt baths and spherical pores. No porosity is found in the mixing zone metal.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
