项目摘要
Aluminum/Boron nitride nanotube (BNNT) composites with up to 5 wt% (i.e. 9.7 vol%) nanotube fractions were prepared via various powder metallurgy routes, namely, Spark Plasma Sintering (SPS) and High Pressure Torsion (HPT) methods. Optical microscopy, transmission electron microscopy, scanning electron microscopy, X-ray diffraction, and energy dispersive X-ray analysis confirmed the integration of the two phases into decently dense and compact composites. No other phases, like Al borides or nitrides, form in the Al-BNNTs macrocomposites of the two series. The hardness of HPT samples was drastically increased with increasing BNNTs content in Al pellets. The value for Al-BNNT 3.0 wt% sample was more than doubled (190 MPa) compared to a pure Al HPT compact (90 MPa). And the room temperature ultimate tensile strength of Al-BNNTs HPT samples containing 3.0 wt% BNNT (~300 MPa) became ~1.5 times larger than that of a BNNT-free HPT Al compact (~200 MPa).
通过各种粉末冶金路线,即放电等离子烧结(SPS)和高压扭转(HPT)方法,制备具有高达5wt%(即9.7vol%)纳米管分数的铝/氮化硼纳米管(BNNT)复合材料。光学显微镜,透射电子显微镜,扫描电子显微镜,X-射线衍射,和能量色散X-射线分析证实了这两个阶段的集成成相当致密和紧凑的复合材料。没有其他相,如铝硼化物或氮化物,形成在两个系列的Al-BNNT宏观复合材料。HPT样品的硬度随着Al颗粒中BNNT含量的增加而急剧增加。Al-BNNT 3.0重量%样品的值是纯Al HPT压坯(90 MPa)的两倍以上(190 MPa)。含有3.0wt%BNNT的Al-BNNTs HPT样品的室温极限拉伸强度(~300 MPa)比不含BNNT的HPT Al压坯的室温极限拉伸强度(~200 MPa)大~1.5倍。
