Aluminum Hydrogen Embrittlement
On the hydrogen embrittlement of aluminum
Aluminum is a metal, which is light and strong, and is widely used in various industries. However, when aluminum encounters hydrogen, it often suffers from hydrogen embrittlement, which is a key issue related to aluminum.
Hydrogen in aluminum, or because of smelting and processing processes, quietly enters. At the beginning, it is hidden but not obvious, and when it accumulates for a long time, its harm gradually becomes. Hydrogen embrittlement of aluminum causes its mechanical properties to decrease sharply, especially its toughness and ductility, which are damaged to the extreme. As a matter of principle, hydrogen atoms migrate between aluminum lattices, gather in defects, such as crystal boundaries and dislocation domains, and gradually form hydrogen molecules, generating internal stress, causing micro-cracks to germinate and expand.
Looking at the actual situation, in the manufacture and application of aluminum, all should be cautious. If the smelting sequence, the source of hydrogen must be controlled, the purification process must be carried out, and the hydrogen entering the aluminum must be prevented. When processing, choose the appropriate method to avoid hydrogen embrittlement. When using aluminum utensils, it should also be prevented from being in the hydrogen-rich environment, if it is wet and acidic.
To solve the problem of hydrogen embrittlement of aluminum, researchers have devoted themselves to it. Research new metallurgical methods to efficiently control hydrogen; explore new material properties, hoping to increase the resistance of aluminum to hydrogen embrittlement. Or develop monitoring techniques to detect the hydrogen state in aluminum early and take precautions in advance.
The hydrogen embrittlement of aluminum is a hindrance to aluminum use, but with advanced scientific research, we will be able to find a way to solve the problem, so that the advantages of aluminum can be fully developed and more ambitious in various fields.
