Constant strain rate along different crystallographic directions was employed to obtain the elastic stiffness coefficients while considering the anisotropic behavior of the material. Dependence of the elastic moduli on the atomic composition of copper-silver in selected ranges from 20-80\% and the effect of temperatures from 300-600 K on these properties were also investigated. It is found out that the elastic moduli increase with increasing copper concentration while decreases in value as temperature is increased.}, author = {Jan Fronimarc D. Viloria and Francis N. C.

The simulation was conducted using an embedded atom model (EAM) potential and the alloys were subjected to a rapid cooling from 1273 K to 298 K. Deformation process was performed along different crystallographic directions at a constant strain rate. The calculated elastic constants of quenched FeNi and FeCr alloys are in good agreement to experimental data with 1-12\% difference in values. Accuracy of the results were associated with the structural phase and transferability of the EAM potential at higher temperatures.}, url = {http://paperview.spp-online.org/proceedings/article/view/121}, author = {Jan Fronimarc D.
