研究了纳米SiCp/Al 2014复合材料的高温拉伸性能。纳米SiCp能显著提高Al 2014合金的493 K拉伸强度，且不影响合金的塑性。0.5vol%的纳米颗粒对基体合金的强化效果上级4vol%的微米颗粒。
The tensile properties at elevated temperature of nano-SiCp/Al2014 composites have been investigated. The nano-SiCpcan remarkably improve the tensile strength at 493 K of Al2014 alloy without sacrificing the ductility. The strengthening effect for the matrix alloy of 0.5 vol% nano-particles is superior to that of 4 vol% micron-particles.
