Achieving balanced strength-ductility of heterostructured TiC/graphene nanoplatelets (GNPs) reinforced Al matrix composites by tuning TiC-to-GNPs ratio
Abstract Heterostructured Al/10 vol%(TiC-GNPs) composites were produced by powder
metallurgy (PM) with different TiC-to-GNPs volume ratios. As the TiC-to-GNPs ratio
decreases, the improved dispersion of TiC in the matrix is achieved and the heterostructure
of the composite is optimised due to the decreased TiC fraction and increased interaction
between TiC and GNPs. Besides, compressive properties of the composite are improved
significantly, and a balance of the significantly increased strength (σ YS of 481.0 MPa and σ …
