Abstract
The influence of anisotropy on dissimilar aluminum alloy FSW joints were studied by changing the welding direction and advancing side materials. The results show the significant differences in both mechanical properties and microstructure of the welded joints. The 0°7AS joint has the highest tensile strength (414 MPa), reaching 87 % of the 2A12 aluminum alloys strength. The 0°7AS joint has the smallest average grain size in the weld nugget, and the best recovery and recrystallization ability. In the HAZ, the strongest texture types of the 0°7AS and 45°7AS joints are different. The 0°7AS joint has the highest texture strength, with a prominent {011} <211> brass texture. This paper provides the guidance for aluminum alloys welding.
期刊介绍：
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
