Toughening Mechanism of Silicon Whiskers and Alumina Fibres (γ-Al2o3) Reinforced Ni-Al Matrix Composites Through “sintering + Forging”

Abstract

In this study, the microstructural formation and static/dynamic compression behaviour of recycled Ni-Al-Cu matrix hybrid composites reinforced with silicon whiskers and alumina (Al2O3) fibres will be studied. It is intended to be an alternative to traditional alloys/composites used in the aeronautical industry. These composites generally are produced using by combined “sintering + forging” processes. The static and dynamic properties will be evaluated in detail, considering the relevant scanning electron microscopy (SEM) microstructures (including the distribution of reinforcement elements). © 2023, The Society for Experimental Mechanics, Inc.
