## Description

- description: Mo2NiB2-Ni cermets, a type of boride-based cermet, exhibit attractive
    mechanical properties such as high hardness and good wear resistance. However,
    the mechanical properties of these cermets have predominantly been evaluated at
    room temperature. In this study, three-point bending tests were conducted at high
    temperatures to investigate the mechanical properties and fractography of Mo2NiB2-Ni
    cermets. A ternary Mo2NiB2-Ni cermet was prepared using a calcination process
    to synthesize Mo2NiB2 before intering. The calcination process resulted in finer
    and more uniform Mo2NiB2 particles, enhancing the microstructure. Consequently,
    hardness and transverse rupture strength (TRS) were improved. Three-point bending
    strengths were measured for samples measuring 4.0 × 3.0 × 24 mm at temperatures
    up to 800°C in an argon environment, using silicon carbide jigs with a 16 mm span.
    The results indicated that TRS remained approximately constant at about 1.6 GPa
    up to 500°C but decreased sharply above 600°C, reaching about 0.12 GPa at 800°C.
    This decrease was attributed to the softening of the nickel binder phase, which
    adversely affected the TRS.
