TL;DR: In this paper, the results of an experimental and numerical study conducted on a closed-cell aluminium foam that was subjected to uniaxial compression with lateral constraint were reported. And the results showed that regions with higher degrees of anisotropy in the undeformed foam have a tendency to initiate the onset of cell collapse.
83 citations
TL;DR: In this paper, the application of different cooling rates as a strategy to enhance the structure of aluminium foams is studied, and the potential to influence the level of morphological defects and cell size non-uniformities is investigated.
73 citations
TL;DR: In this article, the authors studied microporosity in the metallic matrix of aluminium foams produced by the powder metallurgical route both with and without application of a blowing agent.
67 citations
TL;DR: In this article, the authors investigated the reason for the frequent occurrence of cell wall defects in metal foams and found that aluminium foams often expand during solidification, a process referred as solidification expansion (SE).
56 citations
TL;DR: In this article, an experimental investigation into the constant stress amplitude compression-compression fatigue behavior of closed-cell aluminum foam, both with and without lateral constraint, was conducted, and the early stages of strain accumulation due to fatigue loading are independent of constraint, the rapid strain accumulation stage behaviors are sensitive to the constraint.

TL;DR: Porous metals and metallic foams are presently the focus of very active research and development activities as discussed by the authors, with particular emphasis on research presented at the latest International Conference on Porous Metals and Metallic Foams (MetFoam 2007).
Abstract: Porous metals and metallic foams are presently the focus of very active research and development activities. There are currently around 150 institutions working on metallic foams worldwide, most of them focussing on their manufacture and characterisation. Various companies are developing and producing these materials which are now being used in numerous industrial applications such as lightweight structures, biomedical implants, filters, electrodes, catalysts, and heat exchangers. This review summarizes recent developments on these materials, with particular emphasis on research presented at the latest International Conference on Porous Metals and Metallic Foams (MetFoam 2007).

TL;DR: This work gives an overview of the production, properties and industrial applications of metal foams, with special interest in the mechanical and functional aspects, but also taking into account costs and feasibility considerations.
Abstract: This work gives an overview of the production, properties and industrial applications of metal foams. First, it classifies the most relevant manufacturing routes and methods. Then, it reviews the most important properties, with special interest in the mechanical and functional aspects, but also taking into account costs and feasibility considerations. These properties are the motivation and basis of related applications. Finally, a summary of the most relevant applications showing a large number of actual examples is presented. Concluding, we can forecast a slow, but continuous growth of this industrial sector.

TL;DR: The history of metallic foams and the key innovations that have led to the variety of processing methods known today are reviewed in this article, where it is evident that the idea of foaming metals is very old and that most of the techniques used today have been proposed already in the 1950s.
Abstract: The history of metallic foams and the key innovations that have led to the variety of processing methods known today are reviewed. It is evident that the idea of foaming metals is very old and that most of the techniques used today have been proposed already in the 1950s. The most important milestones in the development of foaming technologies and the some of the attempts to commercialise metal foams are reviewed.

TL;DR: There have been a number of techniques for aluminum grain refining as mentioned in this paper, which can be classified as four categories as follows: grain refining by vibration and stirring during solidification, rapid solidification and severe plastic deformation.
Abstract: Aluminum becomes the most popular nonferrous metal and is widely used in many fields such as packaging, building transportation and electrical materials due to its rich resource, light weight, good mechanical properties, suitable corrosion resistance and excellent electrical conductivity. Grain refinement, which is obtained by changing the size of grain structure by different techniques, is a preferred method to improve simultaneously the strength and plasticity of metallic materials. Therefore, grain refining of aluminum is regarded as a key technique in aluminum processing industry. Up to now, there have been a number of techniques for aluminum grain refining. All the techniques can be classified as four categories as follows: grain refining by vibration and stirring during solidification, rapid solidification, the addition of grain refiner and severe plastic deformation. Each of them has its own merits and demerits as well as applicable conditions, and there are still some arguments in the understanding of the mechanisms of these techniques. In this article, the research progresses and challenges encountered in the present techniques and the future research issues and directions are summarized.
