Metal foam is a cellular structure consisting of a solid metal with gas-filled pores containing a large volume fraction. There are two types of metal foams: closed-cell foam and open-cell foam depending on whether the pores are sealed or interconnected.
Metallic foams can be made of aluminum, steel, copper or nickel. They are the new generation porous functional materials with unique structure and properties. E.g. high specific surface area, small density, ultra lightweight, good thermal & …
Metal foam is a cellular structure made up of a solid metal containing a large volume fraction of gas-filled pores. These pores can either be sealed (closed-cell foam), or they can be an interconnected …
Metal foams are solid structures, usually composed of a dense outer layer, with the inner portion in the form of a matrix of pores. Foams possess the property of 'porosity', allowing air/gas and even liquids to pass through them and they are based on materials with a similar structure, such as natural bone, pumice stone and natural sponges.

Ceramic and Metal Foam Advantages. Virtually any material that can be deposited by chemical vapor deposition can be used to infiltrate a foam and coat the ligaments. Once the coating fills ~5% of the original pore space, the mechanical, thermal, and electrical properties of the whole are dominated by the properties of the coating.

Using composite metal foam (CMF), scientists at the North Carolina State University have developed a bulletproof material that can stop the ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even …
Amorphous metal foams (AMFs) are also known as foamed metallic glasses. They may have great promise as structural material due to their great strength, high hardness, and favorable resistance to wear and fatigue, but metallic glasses are often devoid of ductility, which severely limits their use in traditional engineering applications [ 2 ].
Metal foams are still very expensive due to the complicated and energy-intensive manufacturing procedure. As against conventional bulk metals and alloys such as stainless steel; composite metal foams expand at a relatively constant pace on being exposed to high heat.
metal(lic) foam: foams are special cases of porous metals. A solid foam originates from a liquid foam in which gas bubbles are finely dispersed in a liquid. metal sponge: space is filled by pieces of metal that form a continuous …
Metal foams are produced by creating a multitude of gas-filled bubbles in a metallic melt and allowing these to agglomerate, after which the liquid is solidified to a solid foam. There are different ways to form such foams, differing by the type of gas source, the state of metal used (solid or liquid), the way the bubbles are stabilized and by ...
Metal foams are attractive for lightweight construction in the automotive sector since they provide high-energy absorption and good damping properties, which is crucial, e.g., for crash structures.
Afsaneh Rabiei [email protected] 919.513.2674. Matt Shipman [email protected] 919.515.6386. Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less than half as much.

Metallic foams, therefore, appear to be stabilized by solid particles. The action of foam stabilization is not entirely clear yet, but some current ideas on metal foams have been published 19,21,25 as well as general information on foams. 20 …
The foam-like structure of metal foam has many useful applications for the future of our daily lives. It is a new material that has been produced and commercialized by many companies for the past two decades. Although its production has …
A metal foam is a cellular structure consisting of a solid metal with gas-filled pores comprising a large portion of the volume. The pores can be sealed or interconnected. The defining characteristic of metal foams is a high porosity: typically only 5 25% of the volume is the base metal. The strength of the material is due to the square cube law.
Metal foam is exactly what you might think – a cellular structure made from metal with tiny pockets of space inside. What makes Rabiei's metal foam better than others is that she's been able ...
A metal foam is a cellular structure consisting of a solid metal, frequently aluminum, containing a large volume fraction of gas-filled pores. The pores can be sealed ( closed-cell foam ), or they can form an interconnected network …
