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

The paper is devoted to the study of stress corrosion cracking phenomena in friction stir welding AA-2024 T3 joints. Constant load (CL) cell and slow strain rate (SSR) tests were carried out in aerated NaCl 35 g/L solution. During the tests, open circuit potential (OCP) and electrochemical impedance spectroscopy (EIS) were measured in the different zones of the welding. The results evidenced initial practical nobilty of the nugget lower compared to both heat-affected zone and the base metal. This effect can be mainly ascribed to the aluminum matrix depletion in copper, which precipitates in form of copper-rich second phases. In this zones, no stress corrosion cracking was noticed, but well-evident stress-enhanced intergranular corrosion occurred. This is due to the uneven distribution of platic deformation during the slow strain rate tests. Higher strain values are localized at the heat affected zone, where softening occurs. On the contrary, stress values at the nugget are not sufficient to favor both the initiation and propagation of stress corrosion cracks. In the range of processing parameter studied in this experimental work, the stress corrosion cracking susceptibility of the friction stir welding (FSW)-ed alloy is then similar to that of the base metal.

Abstract Intergranular corrosion of stabilized austenitic stainless steel is not accelerated when this material is explosion-clad to carbon steel. Heat-treatment in the sensitization range causes carbon diffusion across the bond interface and precipitation of chromium carbides; this influences the corrosion rates within the diffusion band. Outside of this relatively small area, corrosion rates are similar to those characteristic of nonclad material subjected to the same heat treatment. Stress corrosion cracking of both a stabilized and an unstabilized grade of austenitic stainless steel is not accelerated by explosion cladding to carbon steel. Stainless steel-to-steel explosion clads thus do not appear to pose any special corrosion problems.
