Alumina, Mechanical Properties, Structure of Nickel, Aluminide Composites

In this research work, Ni-Al alloy (Ni-25wt%Al) was designed and produced, composites were developed from the alloy using alumina as reinforcement material at varying weight percentage ranging from 5wt% to 30wt% using stir casting process for the production. Microstructures of the specimens were investigated using metallurgical microscope. Effects of weight percent alumina on the mechanical and physical properties (hardness, toughness, ultimate tensile strength, percentage reduction and density) nickel-aluminides were studied under ASTM standards. Tensile, hardness, impact and compressive tests were performed to understand the change in mechanical properties with respect to corresponding changes in composition. The results showed that ultimate tensile strength increased as the alumina content increased from 0wt% (619 MPa) to 10wt% (630 MPa), the hardness value of the composite decreased with increase in alumina content. The absorbed energy and percentage reduction of the composites decrease with increasing alumina. Comparatively, Ni-25wt%Al + 10wt% alumina gives better properties within the experimental conditions
