Directionally solidified eutectic of the B sub(4)C - ZrB sub(2) system

An investigation was made of reactions in the Zr - B - C system. The existence of a eutectic in the quasibinary section B sub(4)C - ZrB sub(2) was confirmed. A directionally solidified eutectic alloy was obtained by zone melting. Its composition was precisely determined as (mol. %) 71.5 B sub(4)C, 2...

Summary:An investigation was made of reactions in the Zr - B - C system. The existence of a eutectic in the quasibinary section B sub(4)C - ZrB sub(2) was confirmed. A directionally solidified eutectic alloy was obtained by zone melting. Its composition was precisely determined as (mol. %) 71.5 B sub(4)C, 28.5 ZrB sub(2). The effect of melting parameters on the eutectic structure was studied.
