A Review on Prodution of Aluminium Metal Foams

Abstract

Abstract:Aluminum metal foam has wide applications for lightweight construction has become an attractive research field. In this review paper, the various possible methods for Aluminium metal foams production and other cellulose metallic structures are studied. According to the state of matter the different production processes are classified into three ways solid, liquid and gaseous. Metal foams have a unique property such as light weight in combination with higher compression strength, lower specific weight, high stiffness and better energy absorption quality. Production of metal foams is a very difficult task because of the simultaneous occurrence of solid, liquid and gaseous phase's at different temperatures. There are number of technologies and methods of manufacturing foamed metals are available but still the foamed metal suffers from deficiencies and non-uniformities. To improve the foam quality, it is necessary to study and understand the foam stability of liquid metals, which will help production techniques of foam metals more reliable and producible. In this review finds the best suitable method for production of aluminum metal foam for mechanical application. It has been experimentally confirmed that aluminum metal foams produced by the Powder Metallurgy method present high pore connectivity hence there is a chances to get good result when we will do the analysis over application.

Production of Open-Cell Metal Foams by Recycling of Aluminum Alloy Chips

“…Finding new, more efficient and better controllable foam production processes is necessary in order to achieve even better properties. This is also important so that the production process, based on predetermined parameters, achieves precisely defined properties [10].…”

Metal foams: A review for mechanical properties under tensile and shear stress

“…Of course, not all methods can be applied for all metal alloys. Some methods use similar techniques for foaming aqueous or polymer liquids, others developed techniques based on a specific characteristic of materials, such as the action during sintering or the agent they can deposit electrically (Banhart, 2013;Mahadev et al, 2018;Kulshreshtha and Dhakad, 2020;Parveez et al, 2022). The basic processing techniques of cellular materials are summarized in Ashby et al (2000a), with the main categories: liquid metallurgy, coating techniques, and powder metallurgy.…”

Fabrication of Al/SiC composite foams with TiH2 foaming agent by laser melting deposition

“…Due to the exceptional performance on energy absorption, sound insulation, and electromagnetic shielding, aluminum foams (Al foams) are widely used as structural and functional materials in aerospace, automobiles, and transportation fields [1][2][3][4]. Various methods, including melt foaming [5][6][7] and powder metallurgical [4,[8][9][10], have been developed to manufacture Al foams with different porosity. However, Al foams fabricated by these traditional methods have low flexibility for adjusting pores' shape, size, and distribution [11][12][13].…”
