## Description

- description: "Eutectic particles of B4C-TiB2 were reinforced with Ti by spark plasma
    sintering (SPS) or\r\ninfiltration. The SPSed samples with 20, 30 and 40 wt. %
    Ti consisted of ceramic phase, and had\r\na bicontinuous macrostructure formed
    by the Ti-rich region and the eutectic particles region,\r\nwhile the infiltrated
    sample was a complex composite comprised of a 3D Ti-rich continuous\r\nnetwork,
    composite in nature, that contained Ti-metal and in which are embedded isolated\r\nceramic
    (eutectic) particles. The SPSed samples are brittle with the maximum bending strength\r\nof
    300 MPa for the 30 wt. % Ti, higher than for a reference sample produced by SPS
    from\r\ndirectionally solidified eutectic particles. A higher amount of added
    Ti results in a higher\r\ndisplacement in the bending test suggesting a higher
    fracture toughness. Simultaneous\r\nstrengthening and toughening of the composite
    was realized. The infiltrated sample was ductile,\r\nwhile its bending strength
    (220 MPa) was comparable to the values measured for the brittle asintroduced\r\nreference
    sample and the sample with 20 wt. % Ti, both produced by SPS. In the\r\nSPSed
    and infiltrated samples at the interface between the Ti-rich region and B4C-TiB2
    eutectic\r\nparticles, a local ‘pull-out’ intergranular fracturing mechanism mainly
    involving Ti-B 1D-grains\r\nwas observed. This local micromechanism together with
    a ‘pull out’ macromechanism of the\r\neutectic grains from the Ti-rich component
    are considered important for the bridging/anchoring\r\nbehavior responsible for
    the strengthening and toughening processes in our novel hierarchical\r\ncomposites."
