"For a rather long time, basic research projects have been focused on examinations of mechanical properties for Rapid Solidification Powder (RSP) steels. These state-of-art steels are commonly known as %22powdered steels%22. In fact, they combine distinctive attributes of conventional steel alloys with unusual resistance of construction material manufactured by so called %22pseudo-powdered%22 metallurgy. Choice of suitable materials for experimental verification was carried out based on characteristic application of so called %22modern steel%22. First, groups of stainless and tool steel types (steel grades \u010DSN 17 and 19) were selected. These provided representative specimens for the actual comparison experiment. For stainless steel type, two steel types were chosen: hardenable X47Cr14 (\u010DSN 17 029) stainless steel and non-hardenable X2CrNiMo18-14-3 (\u010DSN 17 350) steel. They are suitable e.g. for surgical tools and replacements (respectively). For tooling materials, C80U (\u010DSN 19 152) carbon steel and American D2 highly-alloyed steel (\u010DSN %22equivalent%22 being 19 572 steel) were chosen for the project. Finally, the M390 B\u00F6ler steel was chosen as representative of powdered (atomized) steels. The goal of this paper is to discuss structural aspects of modern stainless and tool steel types and to compare them against the steel made by the RSP method. Based on the paper\u00F6s results, impact of powdered steel structural characteristics on the resistance to crack initiation shall be evaluated."@en . "4"^^ . "60" . "3"^^ . . "154499" . .
