In today's world, compared to previous years; Science and technology have made great progress, industrial areas have expanded and the demand for metal foams, which are light and durable materials in many sectors, has increased day by day. Metal foam materials, due to their promising properties with their low density, high impact absorption and similar properties, have become remarkable materials in many areas such as structural applications, automotive industry, defense industry and aerospace industry in recent years. AA2024 alloy is preferred in many areas where both safety and lightness are important due to its toughness and resistance to corrosion, as well as impact energy absorption, sound absorption, and usability as a functional material. In this study, aluminum foam production with closed pore structure was studied by adding TiH2 powders as a blowing agent to AA2024 alloy powders with an average powder size of 220 μm by powder metallurgy method. For the production of aluminum foam material, AA2024 alloy powders and 1 wt% of pre-heat treated TiH2 powders were mixed mechanically. Then, the obtained powder mixture was molded, pressed, and sintered in the furnace under an inert gas atmosphere. The foaming behavior of the bulk sample, which was applied hot pressing after sintering, was investigated depending on these parameters by foaming at temperatures ranging from 750 to 800℃ in the furnace environment and foaming times of 10 minutes to 30 minutes at these temperatures.
