对Zr0.39Ni0.61和（Zr0.39Ni0.61） d0.59非晶合金进行了中子衍射和x射线衍射及反向蒙特卡罗（RMC）模拟，研究了氘吸收对金属原子的重排作用。RMC模型表明，吸收氘后，Zr-Zr的距离略有增加，而Zr-Ni和Ni-Ni的距离基本保持不变。此外，RMC构型的Voronoi多面体分析表明，Zr0.39Ni0.61和（Zr0.39Ni0.61） d0.59非晶合金在Zr和Ni周围的局部组织没有太大差异。
Neutron and X-ray diffraction and reverse Monte Carlo (RMC) simulation were performed on Zr0.39Ni0.61and (Zr0.39Ni0.61)D0.59amorphous alloys to investigate the rearrangement of metal atoms due to the deuterium absorption. The RMC models showed that the Zr–Zr distances slightly increase but the Zr–Ni and Ni–Ni distances remain virtually unchanged after the deuterium absorption. Additionally, the Voronoi polyhedral analysis of the RMC configurations showed that there is not much difference in the local structure around Zr and Ni between Zr0.39Ni0.61and (Zr0.39Ni0.61)D0.59amorphous alloys.
