An Al-12Si/Al-3.5Cu-1.5Mg-1Si bimetal with a good interface was successfully produced by selective laser melting (SLM).The SLM bimetal exhibits four successive zones along the building direction:an Al-12Si zone,an interracial zone,a texture-strengthening zone and an Al-Cu-Mg-Si zone.The interfacial zone (< 0.2 mm thick) displays an increasing size of the cells composed of eutectic Al-Si and a discontinuous cellular micmstructure,resulting in the lowest hardness of the four zones.The texturestrengthening zone (around 0.3 mm thick) shows a remarkable variation of the hardness and <001> fiber texture.Electron backscatter diffraction analysis shows that the grains grow gradually from the interfacial zone to the Al-Cu-Mg-Si zone along the building direction.Additionally,a strong <001> fiber texture develops at the Al-Cu-Mg-Si side of the interfacial zone and disappears gradually along the building direction.The bimetal exhibits a room temperature yield strength of 267 ± 10 MPa and an ultimate tensile strength of 369±15 MPa with elongation of 2.6 ± 0.1%,revealing the potential of selective laser melting in manufacturing dissimilar materials.
