Stress Corrosion Cracking of Friction Stir Welding (FSW) of AW 5083 and AW 5059 Aluminium Alloys
Author:
Abstract: Friction stir welding (FSW) joints of AW 5083 and AW 5059 alloys were used for the study. Mechanical properties, resistance to stress corrosion cracking (SCC) were investigated and metallographic tests were performed using an optical and scanning microscope (SEM). The parameters of friction welding are also given. Stress corrosion was investigated by the method of slow strain rate testing (SSRT) in air and 4.5% NaCl aqueous solution. During SCC tests elongation, strength, fracture energy and time to break were measured. Very good strength of the tested alloys was found with good resistance to stress corrosion cracking. The aim of the study was to determine the possibility of using the AW 5059 and AW 5083 friction welded (FSW) alloys in marine structures, using stress corrosion resistance as a criterion
