Bulk Modulus of Copper Alloys in Context of Modern Metal Theory

Le résumé fourni par la source

Abstract The authors used a modern quantum theory allowing to determine the energy levels of electrons in real metal. Based on that analytical equations have been presented by means of which the bulk modulus for chosen metals were calculated. It should be emphasized that all values obtained directly from the derived equation are in perfect conformity with the experimental data, a few percentage differences are comparable with the potential measurement error. Subsequently a simple mathematical model has been proposed which allows to calculate the bulk modulus of copper alloys depending on their percentage composition. The authors performed numerical calculations for the typical copper alloys and the results are presented in the form of graphs.
