Abstract Scope |
Strong and ductile Al alloys are highly desired in aerospace and automobile industries. By processing as-cast alloy via laser rapid solidification techniques, we refine coarse-grained Al-20 wt.% Si alloy into Al-Si nanofibrous composite with nanoscale, fibrous, fully eutectic microstructure. By strategically preparing in-situ tensile samples with different Si nanofiber orientation and colony numbers, we investigated the anisotropic mechanical behaviour of Al-Si nanofibrous composites and deformation incompatibility between different colonies. The present work provides fundamental knowledge to design high performance Al-Si bulk materials using additive manufacturing. This work is funded by DOE, Office of Science, Office of Basic Energy Sciences with the grant number of DE-SC0016808. |
