采用热分析、显微观察和x射线衍射等方法，研究了硼-镍二元体系。结果表明：(1)确定了Ni3B （mp . 1,166°C）和Ni2B （mp . 1,125°C）两种金属间化合物。(2) Ni（固溶体）与Ni3B、Ni3B与Ni2B发生共晶反应。在% B， 1,093℃时共晶点为18.0，在% B， 1,103℃时共晶点为30.0。(3)在850℃时，硼对镍的溶解度小于0.1 at %；在1000℃时，硼对镍的溶解度小于0.2 at %。根据这些结果，编制了Ni-B体系在% B下高达33.3的相图。
The binary nickel-boron system up to 33.3 at % B was studied by thermal analysis, microscopic observation, and by X-ray diffraction. The results are summarized as follows:(1) Two kind of intermetallic compounds of Ni3B (m.p. 1, 166°C) and Ni2B (m.p. 1, 125°C) were confirmed.(2) Eutectic reactions were observed between Ni (solid solution) and Ni3B, and between Ni3B and Ni2B. The eutectic point of each reaction was 18.0 at % B, 1, 093°C and 30.0 at % B, 1, 103°C respectively.(3) The solubilities of boron into nickel were below 0.1 at % at 850°C, and below 0.2 at % at 1, 000°C.From these results, the phase diagram of Ni-B system up to 33.3 at % B was compiled.
