Abstract

Metal matrix composites are demanded broadly in numerous fields of engineering and industrial sectors. In the current study, the effects of rice husk ash on AA6061 was considered by altering RHA at 2%, 4%, 6% and 8% by weight at a stirring speed of 300 rpm. In the present situation, a pattern of aluminium alloy strengthened with RHA particles fabricated by stir casting method at 600 �C and 750 �C pouring temperatures are formed and analysed. Microstructural analysis was carried out for aluminium alloy and aluminium/ RHA composites using an optical microscope. The research shows that as the percentage of reinforcement increases, there is an increase in crystallite size and micrographs results indicate the presence of silica from rice husk ash on aluminium alloy. From the electrical properties examination, The RHA reinforcement increased the conductance of the AA6061 metal matrix thereby, increasing the capacity of the metal matrix to conduct electricity because of the presence of RHA in the developed composites. � 2020 Elsevier Ltd.
