Three causes and solutions to crack in aluminum
Main causes of aluminum profile cracks: 1, aluminum extrusion temperature is too high, the tensile strength of the metal surface decreased, under the action of friction crack; 2.

Many metals tend to develop edge cracks during hot and cold rolling. Edge cracks need to be removed by a trimming operation, and they may cause rupture of the sheet in the rolling mill.
sheet. The edges of the sheet are subjected to tensile deformation . This leads to edge cracks. If the center of the sheet is severely restrained and subjected to excess tensile stress, center split
Explore the causes and effects of stress-corrosion cracking (SCC) in aluminum alloys, with a focus on the role of alloying elements like copper, magnesium, silicon, and zinc. Discover how different
Surface cracking is generally recognised as one of the main defects occurring during the process of aluminium extrusion, especially in the case of the so called hard aluminium alloys.
Microscopic Damage Growth with Hydrogen-induced Longitudinal Cracks in Tensile-shear Test on Mechanical Clinching Joint of Mild Steel Sheet and Aluminum Alloy
Examples of micro-crack development on the top convex surfaces of 0.5 mm thick aluminum 1050 sheets after bending under: a) 200°C, b) 150°C, and c) 100°C. Figures - uploaded by Naser Alsaleh
Residual stresses can be beneficial or detrimental, depending on whether the stress is tensile or compressive. Tensile residual stresses can be large enough to cause component distortion or cracking. Also, fatigue and stress corrosion cracking require the presence of tensile
The application of aluminum alloys in various industries such as automotive and aerospace, is inclusive. In addition, in these industries, holes in these materials are used for bolts and rivets. Accordingly, in this article, the initiation and the propagation of cracks in the 2024 aluminum alloy were detected, by means of two methods including acoustic emission and
The micro crack of aluminum sheet during cold rolling lubricated with emulsions is investigated. Experi-ments show that micro cracks occur after cold rolling process and this is attributed to
The crack surface of steel casting is nearly black, while that of aluminum alloy is dark gray. The external crack can be seen by naked eye, and can be distinguished from cold crack according to the shape and fracture characteristics. which hinders the shrinkage of the casting and produces great tensile stress, resulting in cold cracks in
The results show that the fractal dimension of 5083 aluminum alloy sheet at different tensile deformation temperatures is between 1.77 and 1.79 and the fractal dimension, yield strength, and tensile strength decrease with the growing deformation temperature. Investigation of the stress corrosion cracking behavior in annealed 5083 aluminum
