IConAMMA 2018 Study on Mechanical Properties of LM 6 Aluminium Alloy Reinforced With Ground Granulated Blast Slag (GGBS) Particles Manoj Kumar Ch a , Rajendra Kumar N b , Thenarasu M c,* a Department of Mechanical Engineering, Amrita School of Engineering, Amrita Vishwa VidyapeethamCoimbatore641112, India 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. © 2018 Elsevier Ltd. All rights reserved.

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
