Ultrasonic peen forming (UPF) is an emerging technology that exhibits great superiority in both its flexible operating modes and the deep residual stress it produces compared with conventional plastic methods. Although ultrasonic transducers longitudinal vibration have been widely studied, they seldom incorporated into UPF devices for machining confined spaces. To meet requirements of this type...

Dissimilar friction stir welding joints are widely employed in the industrial field due to excellent microstructural and mechanical properties of resulting joints. Nevertheless, further enhance weld properties, addition reinforcement particles on joint-line during process has been proven effective for increasing its performance. In present investigation, microstructure impact behaviour FSWed be...

A finite element model of the protection mechanisms offered by Mg-based organic coatings was developed. The predicted change in corrosion potential AA2024-T351 as a function pH, water layer thickness, and inhibition oxygen reduction reaction. pH solution calculated taking into account Mg dissolution, precipitation Mg(OH) 2 , Al hydrolysis 3+ ions. critical value at which sharply decreases to va...
