1 Introduction The production of a metal foam via the powder metallurgical route is a two-step process. First, a precursor is made from powders, which is then foamed in a second step by heating it above the solidus temperature of the alloy composition.

1 Introduction Lightweight materials such as aluminum-based alloys have long been developed and their performance optimized.[1] Therefore, the potential for significant improvement is generally low. A very effective method of improving the properties of aluminum (Al) alloys is the addition of small amounts of the element scandium (Sc).[2] The hardening potential of Sc in Al was first discovered in the 1960s.

1 Introduction The amount of aluminum and aluminum alloys for lightweight applications is steadily increasing, especially due to the increasing electrification of vehicles.[1] More intensive cooperation between aluminum producers, job-shop operators and end manufacturers ahead could open further potential for the use of aluminum alloys.
