In recent years, laser-arc hybrid welding has emerged as a novel technology for aluminum alloy welding, making it essential to investigate the fatigue properties of welded joints. In this paper, 6061 aluminum alloy plate with thickness of 4mm was welded by laser-MIG hybrid welding technology. Optical microscope observations reveal that the upper and lower regions of the hybrid welded joint are influenced by the laser-MIG arc and the single laser, respectively. The energy density and heat input differ between the two, resulting in a smaller equiaxed grain size in the upper part of the weld compared to the lower part. The fatigue limit of the 6061 aluminum alloy welded joint, determined through fatigue testing and S-N curve analysis, is 79.1 MPa for 10<sup>6</sup> cycles. Under cyclic loading with stress amplitudes (<i>σ</i><sub>a</sub>) of 95 MPa and 115 MPa, the fatigue crack initiation sites are located in the sub-surface of the specimens, which contain pores. The fatigue fractures under different stress amplitudes show ductile fracture characteristics.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23452 - 23462"},"PeriodicalIF":2.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dimensional accuracy and mechanical performance tests were conducted on printed samples with different exposure time configurations, and data for different exposure times were collected and subjected to detailed statistical analysis. The experimental results show that with increasing exposure time, the dimensional precision in the X and Y directions initially improves but subsequently deteriorates, whereas the dimensional accuracy in the Z direction remains more stable and is less impacted by variations in exposure time. The highest dimensional accuracy was observed at an exposure time of 3 seconds. Additionally, as the exposure time extended from 2 seconds to 6 seconds, the mechanical characteristics of the samples improved. Microstructural observations of the tensile sample cross-sections revealed that the surface quality of samples exposed for 3 seconds was superior. Balancing high precision and mechanical performance, the optimal exposure time was determined to be 3 seconds.

Ultrafine grains, high density of dislocations and nano-precipitates were obtained after solid solution, cold extruding and aging. Dislocations contribute most, nano-precipitates come in second and grain boundaries last to the strength.
