Abstract

In this paper, production
and properties of Al2024-SiC-B₄C hybrid nanocomposite produced using
mechanical alloying and hot pressing by powder metallurgy method. First of all,
Al2024, SiC and B₄C powders were
alloyed in planetary ball mill at room temperature with 8 hours to be obtained
homogeneous powder distribution. After, the hot pressing technique was
used for producing hybrid nanocomposite with 2 weight percentage (1 wt.% SiC
and 1 wt.% B₄C respectively) of SiC and B₄C
reinforcements. The mechanical (hardness, tensile strength, bending strength,
fracture surface), physical (density, porosity) of properties and
microstructure of Al2024-SiC-B₄C hybrid nanocomposite were
investigated. It was showed that the uniform distribution of dispersion of
SiC-B₄C nano particles within Al2024 matrix.
