Hybrid superplastic formation of magnesium alloys

Superplastic formation has gained its popularity especially in the automotive and aerospace industry due to its ability to form complex components in a single operation with near final dimension finishing. However, its greatest drawback lies in its strict requirement involving expensive material of...

description Superplastic formation has gained its popularity especially in the automotive and aerospace industry due to its ability to form complex components in a single operation with near final dimension finishing.

With the introduction of hybrid superplastic formation, the elimination of the later drawback is targeted to overall improve the attractiveness of superplastic formation to other industries. Hybrid superplastic formation combines a pre-process of deep drawing before conventional superplastic forming.
