摘要

利用x射线衍射和声速测量研究了塑性变形对Pd40Ni40P20非晶合金组织的影响。结果表明，试样的轧制导致了非晶相的结构变化(第一配位球的畸变)，并且在试样的近表面区域结构变化更为明显。滚动也会导致横向声速的降低。观察到的效果随着时间的推移而减弱。结果表明，这些效应与非晶合金的非弹性变形有关。

Influence of deformation on the structural transformation of the Pd40Ni40P20 amorphous phase

The influence of plastic deformation on the structure of the Pd₄₀Ni₄₀P₂₀ amorphous alloy has been investigated using X-ray diffraction and measurements of the velocity of sound. It has been revealed that the rolling of the sample leads to a change in the structure of the amorphous phase (distortion of the first coordination sphere) and that the structural transformations are more pronounced in the near-surface region of the sample. The rolling also results in a decrease in the transverse velocity of sound. The observed effects decrease with time. It has been demonstrated that the revealed effects are associated with the inelastic deformation of the amorphous alloy.
