Abstract : The binary alloy system hafnium-boron has been invetigated by means of X-ray, metallographic, melting point, and differential-thermoanalytical techniques. The experimental alloy material comprised of hot-pressed and heat-treated, arc- and electron-beam melted, as well as equilibrated and quenched alloy material. All phases of the experimental investigations were supported by chemical analysis. The results of the present investigation, which resulted in the establishment of a complete phase diagram for the system, are discussed and compared with previously established system data. (Author)
