New Insights into Fabrication of Al-Based Foam with Homogeneous Small Pore-Structure Using MgCO3/Zn Composite Powder as a Foaming Agent

Porous Structure Fabrication Using a Stereolithography-Based Sugar Foaming Method

Porous structure has wide application in industry due to some of its unique properties such as low density, low thermal conductivity, high surface area, and efficient stress transmission. Both templating and foaming agent methods have been used to fabricate porous structures. However, these methods can only fabricate simple geometries. In recent years, many studies have been done to use additiv...

Production of Nigella sativa Beverage Powder under Foam Mat Drying Using Egg Albumen as a Foaming Agent

The aim of this study was to determine the feasibility of producing Nigella sativa powder under a foam mat drying technique. A central, composite design of experiments was used to optimize the drying condition and compare the solubility, the antioxidant and mineral content of roasted Nigella sativa, and the foam mat dried Nigella sativa powder. Foams were prepared from Nigella sativa solution b...

Toz Metalurji̇si̇ Yöntemi̇ İle Alümi̇nyum Köpük Üreti̇mi̇ Procuction of Al Foams by Powder Metallurgy Route

In this study pure Al and pre-alloyed Al alloy powders (Alumix 231Al-Cu %2.5-Mg %0.5–Si %14) with or without reinforcing elements were used to produce classical Al foam or spherical Al foam with various production parameters by using powder metallurgy route and the results obtained have been discussed. Al2O3 and SiC particles were used as reinforcing elements and TiH2 powders were used as foami...

Guar Foaming Albumin – A Foam Stabilizer

Manufacture of Aluminum Closed-cell Foam by ARB process using CaCO3 as the blowing agent

Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...
