Abstract

Composite materials based on a 5xxx series aluminum alloy strengthened with 0.1 wt % of multiwalled carbon nanotubes (MWCNTs) or 0.1 wt % WC_{1 –x}/MWCNTs were synthesized by high-energy ball milling and subsequent gas extrusion. The structural phase composition and physicomechanical properties of bulk composites are characterized. A comparison with published data on the properties of composites based on 5xxx series aluminum alloys reveals promises of using gas extrusion for consolidation, as well as the effectiveness of the use of strengthening microadditives of MWCNT hybrid nanostructures to increase strength.

气体挤出技术在碳纳米结构增强的5xxx系列铝合金基础上合成高强度复合材料

摘要

通过高能球磨和随后的气体挤出，合成了基于5xxx系列铝合金的复合材料，该复合材料用0.1 wt％的多壁碳纳米管（MWCNT）或0.1 wt％的WC _{1 – x} / MWCNT增强。表征了本体复合材料的结构相组成和物理力学性能。与已发表的基于5xxx系列铝合金的复合材料的性能数据进行比较后，发现了使用气体挤出进行固结的前景，以及使用增强的MWCNT杂化纳米结构的微添加剂来提高强度的有效性。
