Multiwalled boron nitride nanotubes (BNNTs) have very attractive
mechanical and thermal properties, e.g., elasticity, tensile
strength, and high resistance to oxidation, and may be
considered as ideal reinforcing agents in lightweight metal
matrix composites. Herein, for the first time, Al-BNNT ribbons
with various BNNT contents (up to 3 wt.%) were fabricated via
melt spinning in an argon atmosphere. BNNTs were randomly
dispersed within a microcrystalline Al matrix under ribbon
casting and led to more than doubling of room-temperature
ultimate tensile strength of the composites compared to pure Al
ribbons produced at the similar conditions. Keywords:Aluminum;

importance of making lightweight but high-strength structural
materials has long been recognized . These days, metal matrix
composites (MMCs) based on lightweight metals are extensively
used in aerospace and automotive industries. Over the last
decade, much research has been carried out in the field
