Microstructure and electrical conductivity of 7075Al alloy SiC Nano composites

الملخص EN

Analysis using scanning electron microscope (SEM) at high magnification showed that the microstructure of the nano composites exhibited uniform distribution of SiC particles and less porosity.

The experimental results revealed that adding Nano Reinforcement to 7075Al alloy improve the electrical conductivity for the metal matrix composites with 3, 6, 9 wt.

% SiC were adopted in this work.

The maximum enhancements were observed at 9wt.

% SiC of 5200(Ω.
