High-strength aluminum alloys are of increasing interest to the aerospace and automotive industry for critical high-strength components. B-pillars and door beams being of particular interest to the automotive industry Refill friction stir spot welding (RFSSW) offers an attractive means of joining these difficult-to-weld alloys since bulk melting is avoided and no exit hole is left. In this stud...

Aluminum alloy 7075 is an important engineering material for ship structures. However, the corrosion of Al alloys generally exists in various environments, especially marine environment. Currently, behaviors sulfate-reducing bacteria (SRB) environment has not been well-addressed. In this paper, effect SRB on aluminum was studied by adding to real seawater. The microstructure and grain orientati...
