The study of metallic foams has become attractive to researchers interested in both scientific and industrial applications. In this paper, various methods for making such foams are presented and discussed. Some techniques start from specially prepared molten metals with adjusted viscosities. Such melts can be foamed by injecting gases or by adding gas-releasing blowing agents which cause the formation of bubbles during their in-situ decomposition. Another method is to prepare supersaturated…

Lightweight materials were needed in many different areas, especially in order to reduce the required energy in areas such as automotive and aerospace industries. Metallic foams attract attention in
Manufacturing of Cast Metal Foams with Irregular Cell Structure
Metallic foams are materials of which the research is still on-going, with the broad applicability in many different areas (e.g. automotive industry, building industry, medicine, etc.). These
Pressure-Induced Foaming of Metals
Pressure-induced foaming (PIF) of metals is a foaming technique in which blowing agent free compacted metal powders are foamed. The method consists of heating hot-compacted metallic precursors to
Processing and Characterization of Al Foams Stabilized by Mg
In the melt route of aluminum foam production, melts thickened by alloying additions, such as Ca or Mg, can be foamed by creating gas bubbles inside it. In the present work, Al–2Mg foams are produced
Development of a Melt Foaming Process with Particulate Reinforced Aluminum Alloys
This paper reports on investigations by Hutte Klein-Reichenbach and LKR in the course of the development of a new processing technique for cellular aluminum, to produce net shape parts of foamed
An Innovative Method to Produce Metal Foam Using Cold Gas Dynamic Spray Process Assisted by Fluidized Bed Mixing of Precursors
Metallic foams are known for their interesting physical and mechanical properties such as high stiffness, very low specific weight, high compression strength, unusual acoustic and thermal properties
Metal Foams: Production and Stability
Liquid metal foam can be generated by creating gas inside a liquid or semi‐liquid metallic melt which has been pre‐treated in a suitable way. Such foams are self‐supporting disordered structures in
Aluminum Foams—Processing, Properties, and Applications
This article describes manufacturing procedures that produce aluminum foams and have since become industrially important and successful. It discusses the foaming of melts by blowing agents and
Preparation of Cast Metallic Foams with Irregular and Regular Inner Structure
TLDR
Findry methods for the production of metallic foams have the unique advantage of being able to produce even complex shaped parts and can thus be competitive compared to today's established technologies, the output of which is usually only a semi-finished product for further processing.
