The average measured Hv for polycrystalline ReB 2 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 ReB 2 is always lower than that of Ti–B composites. For comparison, the results from Chung et al. were inserted into the figure.
