Conclusions
-
1.
A study was made, using the methods of thermal, x-ray structural, and metallographic analyses of alloys of the system rhenium-boron, and a phase diagram has been proposed for this system.
-
2.
Only the three known compounds Re3B,Re7B3, and ReB2 (“ReB3”) were discovered; the peritectic melting temperatures of the first two of these compounds were found to be about 2150 and 2000°C, respectively, and that of the third compound about 2400°C.
-
3.
The eutectic mixture of Re7B3 and ReB2, containing about 42 at.% B, melts at the lowest temperature (about 1830°C).
