  title={Kornfeinung von Reistkupfer durch chemische Zus{\"a}tze. III},
  author={Oscar L. Bustos and Winfried Reif},
In part III, studies on the grain refining of superpure copper were carried out using melt additions of transition metal, metal borides together with Ca and Al as a function of the additions of transition metal, metal borides together with Ca and Al as a function of the addition rate and casting parameters such as holding time, crucible material and the ambient-conditions. Besides, the refining efficiency of the ternary addition of Al, B and C was also investigated. Measurements of electrical… Expand

Effects of Superheat and Solute Additions on the Grain Size in Binary Copper Alloys
By utilizing data from the literature, we examine the effects of superheat and solute additions on the grain size (as measured by columnar grain length) in binary copper alloys. Our investigationExpand
