Research project aims at matching the needs of future sustainable manufacture of complex components with the capabilities of powder metallurgical (PM) technique comprised of press&sinter. To realize this, sintered steel performance needs to be brought beyond state-of the art by increased sintered density. We address this problem by exploring how novel ferrous nano-powder as minor addition can work as sintering aid in press&sinter and connect this work with assessment of PM steel surface properties, manufacturing economics and sustainability analysis. The academic constellation takes advantage of their expertise in nanotechnology, powder metallurgy, advanced materials/surface characterization, applied modelling and testing. Co-operation with industry provides test part needed to benchmark the new concepts studied and developed.
