Abstract
Ground Granulated Blast Furnace Slag particles of size 20-50μm were incorporated in LM 6 aluminium alloy by using stir
casting method. The weight percentage of GGBS particles is varied by 1.5%, 2.5%, and 3.5 %. Presence of GGBS particles can
be observed in matrix material by SEM and EDX analysis. The hardness of the composites increased by 35.8 % for 3.5 wt.%
GGBS particles when compared with base LM 6 alloy. The tensile strength of the composites increased by 63.6 % for 3.5 wt.%
composite when equated to the unreinforced alloy. Impact energy is and Percentage of elongation decreased as increasing in wt.
% of GGBS.

1. Introduction
Metal matrix composite (MMC) is a mixture of metal and reinforcement material. To improvise the properties of
the metal matrix, reinforcement can be provided in the form of particles, fibers, or layers. Nowadays researchers
are focusing more on MMCs because of their superior properties than monolithic alloys. MMCs being used as
material aerospace, automobile, marine and industrial applications because of their improvement in strength and
hardness when compared to unreinforced alloys[1].Aluminum alloys have wide applications in various fields due
to their low density, good corrosion resistance, good castability[2]. Due to their low strength and hardness, there is
a limitation in use for many applications. Aluminum metal matrix composites (AMMCs) have increased their
demand in the use of many applications because of their attractive properties like low density, higher hardness,
higher strength and wear resistance[3]. Different methods were used for developing metal matrix composites based
