Preparation and Compressive Properties of Advanced Pore Morphology (APM) Foam Elements
The Advanced Pore Morphology (APM) foam elements were prepared by modified Powder-Compacting Foaming (PCF) method. APM aluminum foam elements have a nearly-spherical surface with closed-cell porous structure and integral skin, with an average diameter of about 15 mm. Their average pore size is 1.879 mm and average equivalent circle circularity is 0.8. Two factors (heating speed and foaming time) played important roles in the preparation of APM foamed aluminum. The deformation of APM foam element exhibits plastic feature under quasi-static compression tests, the elastic region of APM foam aluminum elements is short, and the plastic deformation is not homogeneous.
