“…Aluminum metal foam has been widely used in aerospace, automotive components, civil engineering, renewable energy eld, and biomedical implants due to its lightweight and good mechanical properties [1,2]. The metallic foam has a porous composite structure due to which it possesses excellent strength to weight, ideal thermal, sound, acoustic insulation, and superior impact energy absorption [3][4][5], heat insulation [6] electromagnetic shielding [7]. There are several techniques to produce metal foam ranging from liquid to solid route like direct foaming, space holder, ball making, and casting for the Aluminium metal foam.…”

Aluminum metal foam has become an advanced popular material because it has excellent mechanical and electrical properties and is lightweight. The present work developed the Aluminium metal foam specimen using wax powder as a blowing agent through the powder metallurgy method. The effect of process parameters such as powder size, stirring speed, sintering temperature, and foaming agent content on the mechanical behavior of the developed specimens has been studied experimentally. In the design of experiments, the Taguchi orthogonal L9 array has been implemented. The percentage of Porosity was estimated using the Archimedes principle, and mechanical behaviors such as exural, tensile, and compressive strength were determined. The ANOVA analysis of variance it's been carried out to check the signi cant parameters affecting the mechanical behavior of developed specimens. It was observed that the powder size is the highly signi cant parameter, followed by stirring speed, the content of the foaming agent, and sintering temperature. The Maximum Porosity 71.30%, Compresssion strength 12.01MPa, Tensile strength 6.16 MPa, Flexural strength 5.18 MPa. The microstructure study reveals that there is no any adequet compostion in the specimen. The novelty in this research work is using a novel foaming agent as a Wax powder to develop aluminium metal foam and attained good properties.
