The Ni-Pt phase diagram was corrected in the range of 15–85 at.% Pt and in the temperature range of 400–525 °C using powder X-ray diffraction data. To reduce the time required to achieve the equilibrium state, Ni-Pt alloys, consisting of 80–140 nm nanocrystalline particles (nanoalloys) were used as initial samples. The nanoalloys were synthesized by thermolysis of specially prepared multicomponent
使用粉末 X 射线衍射数据在 15-85 at.% Pt 范围内和 400-525 °C 温度范围内校正 Ni-Pt 相图。为了减少达到平衡状态所需的时间,由 80-140 nm 纳米晶颗粒(纳米合
金)组成的 Ni-Pt 合
金用作初始样品。纳米合
金是通过热解专门制备的多组分前体合成的。通过 X 射线衍射原位研究了系统在高温下的相变。Ni 1-x Pt x (A1)、Ni 3 Pt (L1 2 )、NiPt (L1 0 )、NiPt 3 (L1 2 )单相区域的边界位置被修正。
