Title (EN) COMPOSITE MATERIALS COMPRISING A HARD CERAMIC PHASE AND A CU-NI-MN INFILTRATION ALLOY
(FR) MATÉRIAUX COMPOSITES COMPORTANT UNE PHASE CÉRAMIQUE DURE ET UN ALLIAGE D'INFILTRATION DE CU-NI-MN
Abstract: front page image
(EN) Composite materials comprising a hard ceramic phase (16) and an infiltration alloy (20) are disclosed. The hard ceramic phase (16) may comprise a carbide such as tungsten carbide and/or cast carbide. The infiltration alloy (20) is a heat treatable Cu-based alloy comprising Ni and Mn. The infiltration alloy (20) may be substantially free of Sn and Zn. The composite material is heat treated in order to improve its mechanical properties. For example, the composition of the Cu-Ni-Mn infiltration alloy (20) may be selected such that its hardness, wear resistance, toughness and/or transverse rupture strength are improved after the composite material is solutionized, cooled and thermally aged.
(FR)L'invention concerne des matériaux composites comportant une phase céramique dure (16) et un alliage d'infiltration (20). La phase céramique dure (16) peut comporter un carbure tel que du carbure de tungstène et/ou du carbure fondu. L'alliage d'infiltration (20) est un alliage à base de Cu pouvant subir un traitement thermique comportant du Ni et du Mn. L'alliage d'infiltration (20) peut être sensiblement dépourvu de Sn et de Zn. Le matériau composite est traité thermiquement afin d'améliorer ses propriétés mécaniques. À titre d'exemple, la composition de l'alliage d'infiltration de Cu-Ni-Mn (20) peut être choisie de sorte que sa dureté, sa résistance à l'usure, sa ténacité et/ou sa résistance à la rupture transversale sont améliorées après la mise en solution, le refroidissement et le vieillissement thermique du matériau composite.
