摘要 利用小角X射线散射(SAXS)技术测试了Cu-0.69Cr-0.13Zr合金在470℃时效时析出相粒径的统计尺寸。结果表明,Cu-0.69Cr-0.13Zr合金在470℃下时效,保温时间在1.5~3.5 h间,析出相的粒径统计大小为4.97~5.48 nm,析出相粒子随时效时间延长无明显长大;使用透射电子显微镜观测时效温度为470℃时效时间为2.5 h样品中析出相粒子,测量粒径约为5 nm。2种测量方法所获得的析出相粒径尺寸无明显差异,相互吻合较好。证明小角X射线散射法测量Cu-0.69Cr-0.13Zr合金时效析出相尺寸是准确的。该方法可用于测量Cu-0.69Cr-0.13Zr合金时效析出相尺寸,比透射电镜测量方法更具有统计意义和参考价值。 Small angle X-ray scattering technique was used to study the particle size of precipitated phase of Cu-0.69Cr-0.13 Zr alloy aged at 470 °C, and the aging time was from 1.5 h to 3.5 h. The statistical particle size of precipitated phase is 4.97~5.48 nm, and with the aging time increasing, the precipitated phase particles have no obvious growth. When the aging temperature is 470 °C, and the time is 2.5 h, the particle size of the precipitated phase in the sample is about 5 nm measured by the method of transmission electron microscope. The two methods agree well with each other. It shows that the small angle X-ray scattering technique can be used for measuring the size of aging precipitation of Cu-0.69Cr-0.13 Zr alloy and the experimental result is accurate. Compared with the transmission electron microscope measurement, the small angle X-ray scattering technique is of more statistical significance and more valuable.
