Role of processing parameters on microstructural evolution of spray formed Al–2Mg alloy and Al–2Mg–TiO2 composite

Microstructural characteristics of spray formed zircon sand reinforced LM13 composite

“…On the mushy preform these broken dendritic arms float on the surface resulting in equiaxed grain morphology of spray formed composite [17]. The subsequent impingement of the droplets causes turbulent fluid flow and remelting of the deposited droplets [18]. The turbulent flow on the preform surface during deposition of droplets entraps air causing porosity in the resulted composite.…”

Process Parameters Optimization for Producing AA6061/TiB2 Composites by Friction Stir Processing

“…The commonly used reinforcements include Sic, Al2O3, Tic, CNT, Sio2, B4C, Fly Ash, Tio2, Graphite, SiC etc. [4,5,6]. Among the various reinforcements titanium di -boride (TiB2) is of much interest due to its excellent stiffness, hardness and wear resistance.…”

An Overview of the Interactions Between Reinforcements and Al Matrices with Si, Cu And Mg as Alloying Elements in Aluminum Matrix Composites: Case of Oxide Reinforcements

“…Almost all the works found in literature mention the use of this ceramic combined with other reinforcements such as SiC 145 . Otherwise, the preferred manufacturing process is powder metallurgy 146 , with some articles including the TiO 2 addition using welding 147 or spray formed, as the case of Al-2Mg-TiO 2 composite studied by Chaudhury and Panigrahi 148 , who found good interfacial bonding. Venugopal and Karikalan 145 used stir casting to obtain hybrid metal matrix composites AA6061-TiO 2 -SiC and also reported good interfacial strength, but did not make an in depth study of the interfaces.…”
