在纯铜（99.99%）的机械动力学谱的低通量中子辐照在室温下进行的影响。经过辐照的多晶样品在730 K左右出现了一个新的阻尼峰，而未经辐照的单晶样品则没有这种峰。这个峰值可以控制的晶界滑动之间的合作机制，拖曳的点缺陷，遵循位错线和应力辅助断裂的位错从钉扎点产生的辐照过程。
The effects of low-flux neutron irradiation performed at room temperature on mechanical dynamical spectroscopy in pure copper (99.99%) are shown. A new damping peak at approximately 730 K appears in the irradiated polycrystalline samples, which is absent from the unirradiated and single-crystals one. This peak could be controlled by a cooperative mechanism between grain boundary sliding, the dragging of point defects which follow the dislocation line and the stress assisted break away of dislocations from the pinning points which were generated by the irradiation process.
