ABSTRACT
Liquid metallurgy method based aluminum matrix composites (AMCs) are extensively utilized in diverse engineering applications including shipbuilding, structural, nonstructural, automotive, and aerospace owing to their superior strength, weightless, low density, excellent corrosion, and wear resistance. In the present investigation, liquid state technique was employed to prepare the LM4/aluminum nitride (AlN) composites containing four different mass proportion of AlN filler particles content. The weight proportion of filler particles from 0 to 12 wt% at 4 wt% intervals. Scanning electron microscope (SEM) images demonstrated a even dispersal of filler particles in the matrix. The test outcomes discovered that the LM4/12 wt% AlN AMCs had revealed extreme hardness, tensile, compression strength than the nonreinforced base matrix alloy. A considerable enrichment in the tensile strength is associated with the incorporation of AlN particles into LM4 matrix. The manufactured composites reveal high mechanical properties when compared with the alloy without reinforcement. The improvement of those lightweight AMCs with superior mechanical characteristics has a extreme potential to be employed for aircraft, structural and automobile applications.
