## Description

- description: Reactive consolidation of medium entropy diboride in the ZrB2–TaB2–NbB2
    system was performed by spark plasma sintering of diboride powders at 2000 °C.
    The 3:2:1 ratio between Zr, Ta, and Nb showed the highest specific strength at
    room temperature during the initial screening of the mechanical properties. The
    flexural strength gradually decreased from 700 ± 42 MPa at RT to 518 ± 30 MPa
    at 1600 °C with the Weibull parameter exceeding 15. Diborides with an equimolar
    composition did not show a maximum in their strength, fracture toughness or hardness.
