Microstructure and Strengthening Model of Cu-Fe In-Situ Composites.

The tensile strength evolution and strengthening mechanism of Cu-Fe in-situ composites were investigated using both experiments and theoretical analysis. Experimentally, the tensile strength evolution of the in-situ composites with a cold deformation strain was studied using the model alloys Cu-11Fe, Cu-14Fe, and Cu-17Fe, and the effect of the strain on the matrix of the in-situ composites was studied using the model alloys Cu-3Fe and Cu-4.3Fe.
