INFILTRATED SEGREGATED FERROUS MATERIALS

摘要

Layer-by-layer construction of metallic alloys preferably via binder jetting followed by sintering and binder removal to form a porous metallic skeleton which then may be infiltrated with an infiltrant to provide a free-standing metallic part. The part indicates a volume loss of less than or equal to 200 mm3 as measured by ASTM G65-10 Procedure A (2010) and an un-notched impact toughness of greater than or equal to 55 J according to ASTM E21-12 (2012).
