Özet
In this study, Cu-20wt.Sn alloy was produced by powder metallurgy (PM) method by using high purity element powders. The phases in the microstructure of the produced alloy were determined by XRD study. The phase transformation behaviour of the alloy was investigated by DSC and modelling method. Moreover, the Cu-20wt.Sn alloy system was modelled with molecular dynamics (MD) simulation based on modified Embedded Atom Method (MEAM). The radial distribution function (RDF) was calculated to determine the structural properties of system during the phase transformations. The experimental results showed that the transformation (?+?) ? (?+?) occur at temperature above 500°C. The simulation results showed that the phase transformation ?+???+? occurs at 550°C temperature. Our simulation results are in reasonable agreement with the experimental data. © 2020 Elsevier B.V.
