Eksperiment i istraživanje tvrdoće i zatezne čvrstoće u mikrostrukturi hibridnih kompozita sa metalnom matricom od Al - Gr - Fe3O4

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 (Fe3O4) 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 Fe3O4. 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 Fe3O4 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.
