摘要

由spinodal分解产生的Finley分散两相微观结构引起了人们的兴趣，因为它们与增强的机械性能和过多的界面有关，以减轻缺陷相关行为。本研究报道了一种U-50Zr合金在620℃的热退火和550℃的离子辐照下发生了类似spinodal的相分解，而550℃的离子辐照温度太低，无法通过纯热方式引发相变。研究结果对铀锆合金体系及其作为先进核燃料的应用具有广泛的影响。

On Spinodal-Like Phase Decomposition in U-50 Zr Alloy

Finley dispersed two phase microstructures resulting from a spinodal decomposition are of interest as they are associated with enhanced mechanical properties and excessive interfaces to mitigate defect related behavior. This study reports a spinodal-like phase decomposition in a U-50Zr alloy by thermal annealing at 620°C and ion irradiation at 550°C, with the latter temperature too low to initiate phase transformation pure thermally. The results hold broad impact for U-Zr alloy systems and its application as advanced nuclear fuel.
