A study on foaming behaviour of metal powder precursors compacted by cold uni‐axial compression is reported. PM precursors have been produced by pressing the aluminum powders in a cylindrical die, under single or double compaction. Billet densification was characterized by testing the green sample cross‐sections by micro‐hardness measurements. The so obtained hardness maps were correlated to the foamed sample. The results demonstrated the fundamental role played on the powder densification by… 
Influence of Compaction Conditions on the Foamability of AlSi8Mg4 Alloy
Aluminum AlSi8Mg4 alloy foams were produced by the powder compact foaming route using different parameters for the uniaxial powder compaction step. Compaction time, pressure, and temperature were
Effect of Microstructural Anisotropy of PM Precursors on the Characteristic Expansion of Aluminum Foams
This work investigates the causes of the anisotropic early expansion (below the melting point) of powder metallurgical (PM) aluminum foam precursors by evaluating the crystallographic anisotropy
Study on Crack‐like Pores of Al Foams Made via the Powder‐Metallurgy Route
Mechanisms for the formation and disappearance of the crack‐like pores generated during the early stage of Al foaming are investigated. A model for their disappearance process is proposed for the
