An experimental and investigation on the micro-structure hardness and tensile properties of Al-GrFe3O4 hybrid metal matrix composites

Abstract

In the current scenario, aluminium metal matrix composites (AMMCs) are most important as an auspicious high class of materials. Metal matrix composites are emerging as very much endowed materials exclusively in the fields of automotive, aerospace, electrical and electronics for their numerous applications and technical challenging properties. In the present work, a courageous is perfect to prepare and compare the hardness and tensile properties of LM25-graphite (Gr) and LM25-graphite (Gr)-Ferrous oxide (Fe 3 O 4 ) hybrid composites. The composites were primed to make use of stir casting process in which quantity of reinforcement is speckled from 4 wt% of Gr and 3 wt% of Fe 3 O 4 . The prepared composites are characterized by micro-structural studies and tensile properties were estimated as per the standards. The microphotographs of the composites revealed the reasonably homogeneous supply of the particles in composites with a group at a small number of places. The dispersed graphite and Fe 3 O 4 in LM25 alloy contributed to enhancing the tensile strength of the composites. The SEM of the illustration specifies the homogeneous supply of the reinforcement particles in the matrix without any annulled.

Analysis and Experimental Investigation of A356 Aluminium Alloy Hybrid Composites Reinforced with Gr‐FE3O4‐B4C Nanoparticles Synthesised by Selective Laser Melting (SLM)

“…When compared to matrix A356 alloy, the combined BHN value of A356/Gr/ B 4 C is 63.1 and the hardness value of the hybrid composite increased by roughly 56.1 percent. The harder B 4 C ceramic particles are responsible for the increased hardness [39][40][41]. The research used A356 nanoparticles and reinforcements to achieve the better improvement in microhardness demonstrated in Figure 9 and Table 3 4.…”

“…The load value of graphite and iron oxide (2, 4, and 6 percent) increases as the boron carbide reinforcement is increased. 260.10, 290.06, and 325.43 N/mm 2 are the maximum ultimate tensile strengths, respectively [40,41].…”

Wear Behavior and FESEM Analysis of LM 25 Alloy MMHCs Reinforced with FE3O4 and Gr by Utilizing Taguchi’s Technique

“…Suresh et al manufactured LM25-B4C-Gr-Fe3O4based hybrid composites by stir casting route and mechanical behaviors. The consequences explained that LM25-B4C-Gr-Fe3O4 hybrid composites must be investigated as an outstanding material wherever high strength, ultimate tensile strength, and wear resistance are enhanced [16,17]. Radhika et al calculated mechanical properties and wear characteristics of LM25/SiC/Al2O3 hybrid MMCs and fabricated by utilized liquid metallurgy route.…”

Impact of AlN-SiC Nanoparticle Reinforcement on the Mechanical Behavior of Al 6061-Based Hybrid Composite Developed by the Stir Casting Route

“…ese materials are used in a variety of structural applications in a variety of sectors, including marine, aircraft, and automobiles [1,2]. Rail coaches, towers, pylons, military and commercial bridges, aerospace applications, shipbuilding operations rivets, truck frames, and transportation are just a few of the heavy-duty structural uses for aluminium alloy 6061 [3].…”
