采用剪切和冲击两种球磨方式对硼的储氢性能进行了研究。结果发现，剪切模式导致2.05wt%的氢被困在硼中，而冲击模式导致2.93wt%的氢被困在硼中。差示扫描量热法（DSC）被用来研究热诱导的转变，在新鲜的研磨和老化的样品。通过剪切和冲击模式从新鲜研磨的样品获得的DSC迹线是不同的，并且也与从老化样品获得的那些DSC迹线非常不同。这些差异的起源进行了讨论有关的铣削模式应用。
Two milling modes (shearing and impact) were applied to investigate the hydrogen storage properties of boron. It was found that the shearing mode leads to 2.05 wt% hydrogen trapped in boron, while impact mode to 2.93 wt%. Differential scanning calorimetry (DSC) was used to study thermally induced transformations in freshly milled and aged samples. The DSC traces obtained from freshly milled samples through the shearing and impact modes are dissimilar and are also very different from those obtained from the aged samples. The origins of these differences are discussed in relation to the milling mode applied.
