Centrifugal Casting of Nano Crystalline TiB2 Reinforcement Particulate Reinforcement in Al-Alloy Matrix
Abstract: A method of producing Nano size TiB2 particles within an aluminium matrix is the in situ reaction synthesis method, using KBF4 and K2TiF6 potassium based bearing fluxes. The advantages of this in situ reactive process are a small particle size and good particle/matrix interfacial bonding. However, this method is limited to producing low particulate volume percentage material (˂6 vol%). To overcome this limitation, centrifugal casting has been investigated. A series …
