摘要
The phase diagram of the molybdenum-rich portion of the molybdenum-boron system has been studied.Micrographic analysis was employed as the principal method of investigation,supplemented by X-ray dif-fraction and incipient melting studies.The solubility of boron in molybdenum was found to be 0.2% at theeutectic temperature (2050℃) and 0.07% at 1400℃.The hardness of molybdenum decreases slightly withthe increase of boron in the solid solution range,beyond which it increases steadily with further increase inboron content.
