The shortcomings of aluminum alloys are also obvious, that is, they are too brittle. Now scientists have developed new aluminum alloy materials. This shortcoming of aluminum alloys is being changed. By introducing "faults" into the crystal structure of the metal, it can be greatly improved. Material strength, in addition to making the new aluminum alloy material almost as strong as stainless steel, this property can also be used in corrosion-resistant coatings.
From a microscopic level, metal is composed of crystal atoms that are repeatedly stacked layer by layer. When a certain layer is missing, the stack will collapse and break. What is interesting is that these stacked faults can actually make the material stronger. Higher, this feature is introduced into new aluminum materials, which not only increases the strength and ductility of the material, but also improves its thermal stability. The new products are expected to be applied in corrosion-resistant coatings for electronic equipment and vehicles.
