A study on dental nonprecious cast alloys: Part 3Tensile properties in the ternary nickel-copper-manganese alloys: Influence of adding aluminium and indium

The ternary nickel-copper-manganese (Ni−Cu−Mn) cast alloys were studied on hardening by the addition of elements such as aluminium and indium to the ternary alloys. Tensile tests showed that both the 20 Ni−40 Cu−40 Mn (which has the lowest melting temperature of all the Ni−Cu−Mn ternary alloys investigated) and the 50 Ni−30 Cu−20 Mn (with the highest melting temperature) exhibited a ductile behaviour
