| Abstract: | The effects of C-alloying on the microstructure and secondary phase particles of Cu-2.5Fe-0.1P cast alloy were investigated by transmission electron microscopy (TEM), high-resolution electron microscopy (HREM), and image simulation. The mechanical and electrical properties were slightly improved, and grain refinement and fine γ-Fe particles were evident. Additionally, the Fe3P particles were characterized, and abnormally grown Fe3P particles were observed at the grain boundary in the non C-alloyed and C-alloyed specimens. |
