Comparison of the Physical and Mechanical Properties of Composite Materials (Al2024/Boron Fiber Coarse Particles and Al2024/ Boron Fiber Fine Particles) Produced by Powder Metallurgy Technology

In this examination, metal matrix composites (MMCs) were fabricated utilizing powder metallurgy method. Powder metallurgy deals with products and procedures, which utilize raw material as powders that are compacted into the required shape and size utilizing suitable molds. These compacted powders are called Green compacts. The properties of the component delivered by powder metallurgy procedures are impacted by powder characteristics, for example, composition, morphology, particle size, distribution and method of compaction. The initial phase in the powder metallurgy procedure is the arrangement of green compacts. Uniaxial pressing is one of the most broadly utilized compaction techniques for the preparation of green compacts. Aluminum 2024 is reinforced with different sizes of boron fiber particles (i.e. fine and coarse particles) with volume portions as (5, 10 and 15 wt. %). The most significant utilization of aluminum is with boron fiber coarse particles and aluminium with boron fiber fine particles reinforcement of aluminum metal matrix and so on. The samples were prepared by using aluminum alloy powder with 50µm in particle size with reinforced of boron fiber (fine and coarse) particles sizes are50µm and 125µm in, respectively. The picked powders were blended by using a ceramic bowl and stirrer mixing set up at conventionally, in the wake of the blending process, the powders were compacted by utilizing an UTM (Krystal Engg, UTK-40) at 3.6 ton and 12.5 tons as indicated by (ASTM-E8). At long last, the green compacts were sintered at 4600C-4700C for 7 hr. by utilizing an electrical heater with an argon air. There are numerous assessments and tests, accomplished for the created (AL2024/Boron fiber coarse particles and AL2024/Boron fiber fine particles) of the metal matrix composites. The consequences of this examination demonstrated that improving the physical properties (green density, sintered density and densification density) and mechanical properties
