Abstract
Copper-manganese alloys, optionally with potentially other alloying elements, whose compositions are at or sufficiently near the congruent (minimum) melting point of the Cu—Mn system to substantially avoid dendritic growth during solidification. Processes for producing such alloys are also provided, as well as products produced from such alloys.
Claims20
A copper-manganese alloy containing copper and manganese in amounts at or sufficiently near the congruent melting point of the Cu—Mn alloy system to sufficiently avoid dendritic growth during solidification of the copper-manganese alloy to avoid the formation of microporosity attributable to dendritic growth.
A process of producing a copper-manganese alloy containing copper and manganese in amounts at or sufficiently near the congruent melting point of the Cu—Mn alloy system to sufficiently avoid dendritic growth during solidification of the copper-manganese alloy to avoid the formation of microporosity attributable to dendritic growth, the process comprising combining copper and ferromanganese as a source of manganese.
An article formed by solidifying a copper-manganese alloy containing copper and manganese in amounts at or sufficiently near the congruent melting point of the Cu—Mn alloy system to sufficiently avoid dendritic growth during solidification of the copper-manganese alloy to avoid the formation of microporosity in the article attributable to dendritic growth.
