Abstract

In-situ Fe2P reinforced Cu–Fe bulk immiscible alloy with nanotwinned Cu (nt-Cu) was produced by selective laser melting. The immiscible alloy is characterized by ε-Cu, micrometer fibrous Fe2P and nanoscale Fe2P particles. Moreover, many α-Fe particles (∼30 μm) are distributed inside the fibrous Fe2P. Interestingly, large amounts of nt-Cu particles (∼15 nm) are dispersed inside the fibrous Fe2P and nanoscale Fe2P particles (∼200 nm). The combination of in-situ Fe2P and twin boundaries in the Cu–Fe immiscible alloy results in enhanced strength and plasticity with ultimate compressive stress of 896 ± 20 MPa and strain to failure of 19 ± 2%.
