"We used the examples of rhenium diboride (ReB 2) and boron carbide (B 4 C) to demonstrate that the hardness model works for hard and superhard materials. The hardness obtained is consistent with ...

More recently a rather simple compound of the element, rhenium diboride, has attracted some attention because it is one of the hardest of all known substances. Unlike other super-hard materials ...

PHASE diagram equilibrium studies in the binary tungsten–rhenium system show the presence of two phases over the range 0–65 wt. per cent rhenium at 1,500° C (ref. 1). A terminal solid ...
