Conventional stir casting versus ultrasonic assisted stir casting process: Mechanical and physical characteristics of AMCs

Journal of Alloys and Compounds, 2019
Abstract In this study, aluminum matrix composites (AMCs) were developed using two different techniques, conventional stir casting and ultrasonic assisted stir casting. The drawbacks of the conventional stir casting technique were eliminated by employing an alternative process to produce the composite, wherein ultrasonic energy was introduced into ...

Microstructure of stir-cast metals

Materials Science and Engineering, 1984
Abstract The non-dendritic microstructure of stircast metals is discussed in terms of the shape stability produced by a high density of growing solid particles. This high density appears to be due to the fragmentation of the initial dendrites. The model of fragmentation due to the formation and subsequent melting of high energy grain boundaries is ...

Synthesis of boron carbide reinforced aluminum castings through mechanical stir casting

Journal of Composite Materials, 2021
Nuclear energy is the leading clean energy source in the United States with 99 nuclear power plants generating approximately 20% of the country’s electricity. While the growth of the industry helps to reduce our reliance on fossil fuels, there is also an increase in nuclear waste.

Electromagnetic Stirring in Continuous-Casting Machines

Steel in Translation, 2019
Abstract—Industrial continuous casting machines in Russia mainly employ imported electromagnetic-stirring systems located outside the mold. In case of breakage, the stators of such stirreres must be sent back to the manufacturer for repair. To decrease import dependence, an electromagnetic-stirring system that may be completely dismantled has been ...

Electromagnetic stirring for continuous casting

Revue de Métallurgie, 2003
The multiple versions of electromagnetic stirring in continuous casting are described. For long products, linear or rotational stirring appears confusing, but is clarified based on liquid steel flow pattern and metallurgical results. Rotational mould stirring is the predominant application in billet casting.

Stirring phenomena in centrifugal casting of pipes

Applied Scientific Research, 1987
Dans le procede d’elaboration par coulee centrifuge horizontale de tubes d’acier, la vitesse de rotation utilisee conduit a une acceleration de 100 g dans le metal liquide. A cause des forces centrifuges qui en resultent, le metal semble anime d’une rotation en bloc.
