Abstract
Enhancement in the material properties for a specific application is of major concern in all types of industries, e.g., automobile, aerospace, marine, etc., grain size plays an important role in affecting the mechanical and tribological properties of metals and alloys. The present work investigates how the hyper-eutectic Al–Si alloy properties can be affected by the application of multidirectional forging (MDF). Hyper-eutectic Al–Si alloy containing 20%Si was prepared by casting and a 40% reduction in height in each direction at 300 ± 10 ℃ was given using a power hammer machine during forging. The results show that mechanical and tribological properties such as tensile, hardness, density, porosity, and wear properties improved. The microstructural improvement from dendrites to fine grain size also happened and was uniformly distributed after multidirectional forging.
