The average measured Hv for polycrystalline ReB2 and Ti–B composites under different loads shows that the tendency of Hv to decrease becomes weak for large loads, and the measured hardness of ReB2 is always lower than that of Ti–B composites. For comparison, the results from Chung et al. were inserted into the figure.
