对退火良好的Pd和Pd-H合金进行拉伸试验。结果表明，氢的存在不影响合金的屈服强度，但显著提高了合金的应变硬化。这是解释了一个可以忽略不计的溶质拖曳作用的H上的位错的运动，并通过H诱导的增强增殖的位错塑性变形，分别。
Well-annealed Pd and Pd–H alloys were subjected to tensile tests. It is found that the presence of H does not affect the yield strength but enhances the strain hardening of Pd remarkably. This is explained by a negligible solute drag effect of H on the movement of dislocations, and by H-induced enhanced multiplication of dislocations upon plastic deformation, respectively.
