## Description

- description: We report for the first time the effect of temperature on the mechanical
    properties of (Ta1/3Ti1/3Zr1/3)C carbide. Flexural strength and fracture toughness
    were investigated using the three-point bending technique in argon. Using commercially
    available carbide powders with an equimolar ratio and performing spark plasma
    consolidation at 1973°C, we obtained a bulk single-phase medium-entropy carbide
    ceramic with the lattice parameter a= 4.458 Å. The flexural strength and fracture
    toughness at room temperature reached on average 700 MPa and 3.2 MPa m1/2, respectively.
    At 1800°C, local decomposition of the medium-entropy carbide took place as a structure
    with a local chemical gradient was observed after high-temperature tests, which
    increased fracture toughness by 30% (to 4.4 MPa m1/2). © 2020 The Author(s). Published
