小尺寸力学试验的结果会受到所谓的尺寸效应的影响，即当试验规模缩小到微米或更小时，材料会显得更坚固。发生这种情况的尺寸范围已被证明与样品微观结构的变化有关，例如辐照引起的缺陷的增加。为了研究这种响应，CuCrZr合金进行质子辐照和机械测试，使用微压缩的支柱的尺寸范围。结果发现，辐照缺陷占主导地位的外在尺寸效应和沉淀物微观结构的差异的敏感性也有所降低，这表明，尺寸无关的结果可以从更小的测试体积相比，他们的非辐照的同行在辐照材料。最后，比较模型预测的屈服强度的增加和实验测量值，以建立驱动强化行为的关键参数。
The results of small-scale mechanical tests are convoluted by the so-called size effect, whereby materials appear stronger when the scale of the test is reduced to the order of microns or less. The dimensional range over which this occurs has been shown to be linked to a change in sample microstructure, such as the addition of defects induced by irradiation. To investigate this response, a CuCrZr alloy was subjected to proton irradiation and mechanically tested using micro compression of pillars with a range in size. It was found that irradiation defects dominate over the extrinsic size effect and the sensitivity to differences in precipitate microstructure was also somewhat reduced, suggesting that size-independent results could be obtained from much smaller test volumes in irradiated material compared to their non-irradiated counterparts. Finally, comparison was made between the increase in yield strength predicted by models and the experimentally measured values to establish the key parameters driving the strengthening behaviour.
