摘要：
A bulk nanostructured Al-Y-Ni-Co alloy has been synthesized from gas atomized powder by selective laser melting (SLM). The SLM sample exhibits a hybrid microstructure consisting of nano- and submicron-sized intermetallic phases (Al3Y and Al9Co2) in the alpha-Al matrix. Moreover, it shows the presence of solidification cracks and these solidification cracks can be avoided by introducing substrate plate heating. The SLM processed Al-Y-Ni-Co alloy shows a very high yield strength (625 MPa) combined with about 25% fracture strain, indicating that SLM is a highly versatile processing route not only capable to fabricate conventional alloys but also can process such novel materials.
