N2 - To understand the influence of stepwise change of irradiation temperature on microstructural evolution in pure vanadium, ion irradiations were performed at 473/873, 673/873 and 873/473 K. The defect cluster density was strongly affected by the pre-irradiation temperatures. Suppression of interstitial type loop formation was prominent by pre-irradiation at lower temperatures. These results were explained by the appearance of vacancy-rich conditions at the beginning of the higher temperature irradiation due to the reclustering of the vacancies formed in the lower temperatures.
