利用高压电子显微镜观察了A533B钢中自填隙原子簇的一维运动。测量了电子辐照下一维运动的频率和距离。一维运动在室温下经常发生，但在 563K 时仅轻微发生。通过在 473K 及更高温度下退火，一维运动的频率降低。在长时间照射下，减少的运动频率逐渐增加。虽然退火降低了退火前形成的团簇的运动频率，但对于退火后形成的团簇没有检测到运动频率的降低。
One-dimensional motion of self-interstitial atom clusters in A533B steel was observed using high-voltage electron microscopy. The frequency and distance of one-dimensional motion under electron irradiation were measured. One-dimensional motion occurred frequently at room temperature, but it occurred only slightly at 563K. The frequency of one-dimensional motion was decreased by annealing at 473K and higher temperatures. The decreased motion frequency gradually increased under prolonged irradiation. Although annealing reduced the motion frequency of clusters that had been formed before annealing, reduction of the motion frequency was not detected for clusters that formed after annealing.
