Metallic foams are used in various vital industries such as energy storage, biomedical applications, aviation, and aerospace industry, automotive, etc. thanks to their low density, light weight, high surface area and strong structure. Metallic foams, which can be produced in open-porous or closed-porous form using different techniques such as powder metallurgy, liquid metal infiltration and gas injection, are shown among the materials with high potential and expected to have a wider usage area with the advancement of research in this field, since they can be produced from different metals for special applications and can be produced with specific properties such as controllability of the shape and size of the pores in the metal foam structure. In this study, TiH2 powders, which were previously heat treated under protective atmosphere, were added to AA2024 powders at the rates of 1% and 2% by weight, produced by hot pressing under protective atmosphere, and then foamed under constant temperature in the furnace environment for the constant time and metallic foams were produced by powder metallurgy method. The changes in the Brinell hardness values of the produced metallic foams, the pore structure and size of the metallic foams were investigated and the effect of varying TiH2 ratio on the foaming characteristics of AA2024 metallic foams was investigated.
