Anisotropic Compressive Behavior of Zn-22Al Superplastic Alloy Foams Manufactured Powder Metallurgy Process

Closed-cell Zn-22Al alloy foams are produced through powder metallurgy process. Zn-22Al alloy powders and titanium hydride powders were mixed to prepare a precursor. The precursor was manufactured using uniaxial hot pressing. Macro- scopic porosity is as large as 70% in the condition of heating temp...
