Ternary Phase Equilibria in Transition Metal-Boron-Carbon-Silicon Systems. Part II. Ternary Systems. Volume xi. Hf-Mo-B and HF-W-B Systems.

摘要

The 1400 C isothermal sections of the ternary systems hafnium-Molybdenum-boron and hafnium-tungsten-boron have been investigated using X-ray and metallographic techniques. The phase equilibria in both systems are dominated by the hafnium diboride phase, and a new ternary phase was observed in both systems. Cursory melting point investigations were performed in the ternary systems; melting points of the pseudobinary systems HfB2-MoB2 and HfB2-W2B5 were also determined. (Author).
