X射线衍射法测定纳米晶纯铝的平均晶粒尺寸
Determination of Average Grain Size of Nanocrystalline Pure Aluminum by X-ray Diffraction Method
摘 要
对放电等离子烧结制备的纳米晶纯铝样品进行了X射线衍射分析，并以完全退火的硅粉末作为标准样品来分离仪器宽化，提出了物理宽化后通过“积分宽度法”计算纳米晶纯铝平均晶粒尺寸的方法。结果表明：试验纯铝样品的平均晶粒尺寸为73.7 nm，达到了纳米量级。

Abstract
X-ray diffraction analysis of the nanocrystalline pure aluminum sample prepared by spark plasma sintering was carried out, and fully annealed silicon powders were used as the standard sample to separate the instrument widening. The method of calculating average grain size of nanocrystalline pure aluminum sample by using 'integral width method' after extracting the physical widening was proposed. The results show that the average grain size of the test pure aluminum sample is 73.7 nm, and it has reached the nanometer scale.
