Abstract: This paper researched the metal matrix composites (MMCs) and this system used to produce good strength of the aluminium 6061 with fortified with SiC, TiO₂, and magnesium (Mg). That approach to describe the new composites utilising the scanning electron microscope (SEM) and malleable ductile weariness test have analysed. The hybrid composites have increased the strength for a contribution of reinforced particles. The fatigue behaviour of developed composites has analysed at the room temperature for the low cycle fatigue. The working conditions pursued by the low cycle weariness recurrence level 1 to 25 HZ. The diminishing existence of the metal framework in view of the LCF strain sufficiency for the room and hoisted temperature 3,000 C and R = (εmin/εmax) = 0. The experiments deliberate with continuous amplitude for a prearranged strain of amplitude. The disfigured assessment of weariness standard and thoroughly considered the mean pressure an incentive as far as weakness life acquired in the test results.
