| Abstract Scope |
Cu Ni Co Si is a high-strength conductive copper alloy with good process performance, but its composition range is relatively wide (ASTM standards: Ni (1.0-2.0) wt.%, Co (1.0-2.0) wt.%, Si (0.5-1.0) wt.%). The target composition and internal control standards are the primary challenges faced by the actual production of this alloy. This study is based on an advanced cluster plus connected atom model, existing composition standards, and reported compositions in literature. The results were obtained in {[Si - (Ni, Co, Cu) 12] (Si, Cu) 3} 1-2 {Cu16}14 ~Under the framework of a 15 component formula, the composition points within the standard range of CuNiCoSi alloy composition were determined. Through experimental verification, the relationship between organizational structure and strength conductivity was analyzed, and the optimal composition points and internal control standards were determined. |
