Stiff, strong and ductile heterostructured aluminum composites reinforced with oriented nanoplatelets

In this study, we report a liquid-solid reaction method combined with preferential particle orientation for fabricating a heterostructured Al3BC/6061 composite with ultrahigh Young's modulus (105 GPa), high tensile strength (495 MPa) and reasonable ductility (6.2%). The preferential orientation of Al3BC nanoplatelets contributes to the ultrahigh stiffness, and heterogeneous grain structure of the Al matrix facilitates the development of...
