PRODUCTION AND PROPERTIES OF AL2024-2 WT.% (SiC-B4C) HYBRID NANOCOMPOSITE

Abstract

In this paper, production and properties of Al2024-SiC-B 4 C hybrid nanocomposite produced using mechanical alloying and hot pressing by powder metallurgy method. First of all, Al2024, SiC and B 4 C 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.% B 4 C respectively) of SiC and B 4 C reinforcements. The mechanical (hardness, tensile strength, bending strength, fracture surface), physical (density, porosity) of properties and microstructure of Al2024-SiC-B 4 C hybrid nanocomposite were investigated. It was showed that the uniform distribution of dispersion of SiC-B 4 C nano particles within Al2024 matrix.

2D materials-based metal matrix composites

“…h-BN, as a new type of 2D material, can be used as a 'green' alternative lubricant and offer similar tribological properties. To date, many studies have been incorporating graphene, MoS 2 , WS 2 and h-BN as a composite solid lubricant to achieve better tribological performance [76,[116][117][118][119][120].…”
