采用熔体快淬法在Ar气氛中制备了高达5wt.%的纳米/微米氮化硼(BN)相，即多壁BN纳米管(BNNTs)或BN微粒(BNMPs)。用X射线衍射仪、扫描和透射电子显微镜以及内耗测量分析了在80-800℃温度范围内的比较结构特征。对带材进行了室温拉伸试验。这些结果表明，两种添加相在纳米/微米BN埋入后对纯Al基体都有增强作用，且含BNNT的样品具有明显较高的增强效应。在结构分析和内耗数据的基础上，讨论了BN加入量与Al基之间的结构内相互作用。
Melt-spun aluminum ribbons with up to 5 wt.% of embedded nano/micro boron nitride (BN) phases, namely multiwalled BN nanotubes (BNNTs) or BN microparticles (BNMPs), were fabricated by melt-spinning in an argon atmosphere. The comparative structural characteristics were analyzed using X-ray diffraction, scanning and transmission electron microscopy, and internal friction measurements as a function of temperature within an 80–800 K range. Room temperature tensile tests were carried out on ribbons. These revealed reinforcing effects on pure Al-matrices after nano/micro-BN embedment for both added phases with the notably higher numbers peculiar to the BNNT-containing samples. The intrastructural interactions between BN additions and Al-matrices are discussed based on the structural analysis and the internal friction data.
