Abstract
Modification of chemical compositions of two popular steel grades to adapt their properties to peculiar Selective Laser Melting conditions and to expected applications in the tool and die sectors are proposed. A type 316L stainless steel was modified by blending with an atomized alloy rich in carbon, boron and in carbide/boride forming elements. A different strategy was adopted for a H11 tool steel grade that was diluted with a lower carbon alloy in order to increase processability and to reduce cracking tendency during solidification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
