Herein, nanostructured ternary Ni–Ti–B alloy synthesized by mechanical alloying from the elemental Ni, Ti, and B powders by high energy ball milling is described. The synthesized alloy of nominal composition of Ni70Ti10B20 results in the formation of a unique stable phase of Ni21Ti2B6, which happens to be stoichiometrically very close to Ni70Ti10B20 in the cubic symmetry. The synthesized alloy samples also show amorphization together with the formation of nanocrystalline phases of Ni21Ti2B6 at both early and later stages of the alloying process. Thermal analysis carried out on Ni70Ti10B20 induces crystallinity and reveals the formation of crystalline Ni–Ti–B ternary alloy, Ni21Ti2B6, above 523 K, confirming the stability of the ternary crystalline phase of the alloy. The magnetic saturation of the alloy is measured as 0.95 emu g−1 for the starting amorphous phase that increases to 9.05 emu g−1 for the crystalline phase upon annealing. Correspondingly, the coercivity value for the annealed sample is reduced to 70 Oe from 194 Oe for the amorphous phase. This is the first time that an evidence of the stable crystalline Ni–Ti–B ternary alloy is reported.

稳定的纳米结构Ni21Ti2B6相的固相合成和表征
在此，描述了通过高能球磨从元素Ni，Ti和B粉末机械合金化合成的纳米结构三元Ni-Ti-B合金。合成的标称组成为Ni 70 Ti 10 B 20的合金会导致形成独特的稳定相Ni 21 Ti 2 B 6，该化学相在化学计量上非常接近于Ni 70 Ti 10 B 20的立方对称性。合成的合金样品还显示出非晶化以及Ni 21 Ti 2 B 6纳米晶相的形成。在合金化过程的早期和后期。在Ni 70 Ti 10 B 20上进行的热分析引起结晶，并揭示了在523 K以上形成的Ni-Ti-B三元合金Ni 21 Ti 2 B 6的形成，从而确认了该合金的三元晶相的稳定性。合金的磁饱和被测量为0.95鸸鹋克-1的起始非晶相增加至9.05鸸鹋克-1退火后的结晶相。相应地，退火样品的矫顽力值从非晶态的194 Oe降低到70 Oe。这是首次报道稳定的Ni-Ti-B三元合金结晶的证据。
