The paper deals with the possibilities of grain refinement of superpure copper by additions of elements of the groups IIa through VIIIa an IIb through VIb of the periodic table as well as iron as cerium. Effects of addition rate of grain refiners, melt temperature and cooling rate on the grain size were studied. A fully equiaxial structure can be obtained at low pouring temperatures and high cooling rates. Most elements of the groups IIIb through VIb, especially S, Se and Te, have the strongest… 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 investigation… Expand
