Impact of Micro B4C Particulates Addition on Mechanical Behavior of Al2024 Alloy Composites
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 5
Abstract
In this paper an attempt made for investigating the effect of addition of B4C particulates into the Al2024 alloy. Here microstructural study of the 4 wt. percentage Boron Carbide reinforced composite is studied.90-micron size particulates reinforced composite is characterized with some of the mechanical properties. First the Al2024 alloy composite is fabricated using two stage novel Stir casting method and then the reinforced composite is prepared by adding 4 wt. percentage of boron carbide by continuously stirring the molten metal. Scanning electron microscope (SEM) and Energy Dispersive X-Ray Spectroscope (EDS) are two techniques used for microstructural evaluation. SEM had shown the presence of B4C in the matrix with uniform distribution also EDS test confirmed the presence of Boron Carbide in the matrix. Further specimens were prepared according to ASTM standard for mechanical properties like tensile strength, compression strength shear strength and hardness value. The results showed the increase in the value of all mechanical properties after adding 4 wt. percentage of boron carbide.
