The European Powder Metallurgy Association (EPMA) in partnership with RWTH Aachen University, Germany, is in the preliminary stages of establishing two new Club Projects looking at the combination of Additive Manufacturing and Hot Isostatic Pressing (HIP). Research work will be carried out at the Institute for Materials Applications at the RWTH University, and the partners are now seeking industry members to support the projects.
The EPMA is active in a number of research and development Club Projects, which are financed b, and restricted to, a small number of project members. The aim is for research institutes and industry to work together on key areas of interest, as defined by the project members.
The first proposed Club Project centres around the influence of argon on the impact toughness of AM-HIP materials. While argon limits for PM-HIP materials already exist, argon limits for AM-HIP materials are not yet appointed. The research will look to define the limits for argon in AM-HIP materials, and identify how toughness relates to the Ar content before and after HIP.
The second project will focus on using nitrogen as an alternative shielding gas in the AM-HIP approach. Work will question if nitrogen pores can be completely closed by HIP, and what the influence of nitrogen is on the microstructure. Parts produced will undergo fatigue testing and fracture analysis.
