Abstract
To overcome the trade-off between strength and plasticity of traditional particulate reinforced iron matrix composite, a novel Ti@(TiC + α-Fe) core-shell structure reinforced iron matrix composite with high strength and plasticity was designed and fabricated via near-eutectic temperature hot pressing sintering process at 1100 °C for 2 h. The composite consists of three-dimensional Ti@(TiC + α-Fe) core-shell structure and iron matrix. Predominant features of the Ti@(TiC + α-Fe) core-shell structure include a isolated soft Ti core and a continuous hard TiC–Fe shell. The obtained composite reinforced with such core-shell structure reinforcing particulates achieves an unprecedented compressive fracture strain of 43.9% while maintaining high yield strength of 425.6 MPa and ultimate compressive strength of 798.3 MPa. Thus, this work provides a novel material design approach and alleviates the strength-plasticity trade-off of iron matrix composite.
