Methods are disclosed for heat treating a high-carbon steel component, including a high-carbon tool-steel component, printed by powder-based full-melt additive manufacturing, wherein the printed component contains at least 0.2 wt% C and comprises at least 30 vol% of an austenitic phase and wherein the composition of the component may be selected according to a modified Schaeffler diagram. The methods comprise applying a thermal treatment to decompose at least a fraction of the austenitic phase into at least a ferritic phase, austenitization, rapid cooling or quenching to a temperature below which austenite transforms to martensite, and tempering.

Abstract
Methods are disclosed for heat treating a high-carbon steel component, including a high-carbon tool-steel component, printed by powder-based full-melt additive manufacturing, wherein the printed component contains at least 0.2 wt% C and comprises at least 30 vol% of an austenitic phase and wherein the composition of the component may be selected according to a modified Schaeffler diagram. The methods comprise applying a thermal treatment to decompose at least a fraction of the austenitic phase into at least a ferritic phase, austenitization, rapid cooling or quenching to a temperature below which austenite transforms to martensite, and tempering.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
