IMPACT OF CU ADDITIONS ON A STRUCTURE AND MECHANICAL PROPERTIES OF NEAR AND HYPOEUTECTIC SILUMINS

摘要

Paper presents results of investigations defining the role of Cu in forming macro and microstructure of near and hypoeutectic silumins. The following parameters acted as criteria of evaluation: size of grain and dendrites of solid solution α as well as the mechanical properties of tested alloys. Achieved results were presented to forecast the properties of alloys in a function of chemical composition.
