A generalized bond-strength model of hardness was applied to of Re3B, Re7B3, ReB2, Ru7B3, RuB, Ru2B3, RuB2, OsB, Os2B3, OsB2, and metal substituted aluminum diborides of MgB2 type M0.5A10.5B2 (M=Li, Na, Mg, K, Ca, Sc, Ti, V, Y, Zr, Nb, Mo, Tc, Ru, Hf, Ta, W, Re, and Os). The resulting hardness of transition metal borides was found to be within the range of 14.3–28.2 GPa, and metal substituted aluminum diborides 7.2–21.1 GPa. Comparing the results with other semiempirical results and available experimental data shows the applicability of different methods.
