Abstract

The effects of the baking temperature and time on the mechanical properties of Al-Mg-Si alloys laser-arc hybrid welds were investigated. Increasing the baking temperature promoted the precipitation of the nano-sized βʹ, efficiently enhancing the weld seam. Owing to this, the microhardness of the weld seam increased to 96.0 ± 2.4 HV with the high-temperature baking process (220 ℃-0.5 h), leading to a 13% increase in tensile strength. Consequently, the joint coefficient of Al-Mg-Si alloy laser-arc hybrid welded joints reached 0.7, meeting the requirements for automotive industrialization.

高温烘烤强化Al-Mg-Si合金激光电弧复合焊缝

研究了烘烤温度和时间对Al-Mg-Si合金激光电弧复合焊缝力学性能的影响。提高烘烤温度促进了纳米级β′的析出，有效地改善了焊缝。因此，经过高温烘烤（220℃-0.5 h），焊缝显微硬度提高到96.0±2.4 HV，抗拉强度提高13%。Al-Mg-Si合金激光电弧复合焊接接头接头系数达到0.7，满足汽车产业化要求。图形抽象

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
