Abstract

Phase diagram of the Y-B system and isothermal sections of the Y-Fe-B system at 600 and 800 °C were investigated using X-ray diffraction (XRD), electron probe microanalysis (EPMA) and differential scanning calorimetry (DSC) on the annealed alloys. In the Y-B system, temperature of L↔(αY)+YB₂ was determined to be 1294 °C. YB₆ was confirmed to be a stoichiometric compound at 1000 °C. For the isothermal section of the Y-Fe-B system at 600 °C, five ternary compounds (τ₁-τ₄, τ₆) and 10 three-phase regions were observed. But there were six ternary compounds (τ₁-τ₆) and 18 three-phase regions in the isothermal section at 800 °C. Ternary phases were measured to be stoichiometric compounds and the measured solubility of the third element in the binary phases was mostly below 0.5 at.% at both 600 and 800 °C.

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
