Solute redistribution in stir-cast Al-6Cu

Journal of Materials Science, 1989
The solute distribution in stir-cast Al-6 wt % Cu alloy is more uniform than that in the conventionally cast (unstirred) alloy, solidified at the same cooling rate. The Bower-Brody-Flemings model of microsegregation was modified to take account of convective interdendritic (or intercellular) solute transport in the liquid.

Effect of Stir Casting Parameters on Properties of Cast Metal Matrix Composite

Materials Today: Proceedings, 2020
Abstract In the current investigation, aluminium matrix composite (AMC) was successfully fabricated by liquid melt method and the effect of stir casting (SC) parameters namely Temperature (Temperature), Stir Speed S (SS) and Stir Time (ST) on the properties was studied using Taguchi L9 orthogonal array experimental design.

Friction stir welding of aluminium casting alloys

Welding International, 2013
The results of testing friction stir welding quality in relation to EN AC-43200 (AK9) and EN AC-45000 (AK64) aluminium casting alloys are presented. The test joints were made with the use of a welding machine constructed on the basis of numerically controlled milling machines.

Friction Stir Processing of Cast NiAl Bronze

Materials Science Forum, 2007
Friction stir processing (FSP) of cast NiAl bronze has resulted in significant increases in properties including more than doubling the yield greater that 40 percent increase in the threshold fatigue life; all achieved while increasing ductility. These and other strength, greater than a 60 percent increase in tensile strength, and property improvements

Wear loss of stir cast aluminium alloy 8011

Materials Today: Proceedings, 2020
Abstract The dry sliding wear loss behavior of AA 8011 matrix composite manufactured by stir casting process was considered. A regression model was established to predict the wear loss of the prepared composite. The wear test was steered with pin-on-disc apparatus with the controlling three-factor, three-level central composite rotatable design ...

IoT based stir casting system of aluminium MMC

Materials Today: Proceedings, 2021
Abstract In present days, an Internet of Things (IoT) based smart industry was established for casting sections that produces the different components in automobile, construction, railways and shipping. The effect of casting parameters and their performances on quality were analyzed through collected data from the system. A monitoring system has been

Turbulent flow and solidification: stir-cast microstructure

Metal Science, 1978
AbstractA model for turbulent flow is invoked to explain the variation in particle dimension with stirring rate for Al-Cu alloys solidified under violent agitation. Crystal multiplication is explained by a bending, recrystallization, and boundary melting mechanism which is related to the hydrodynamics of the turbulent regime.

In-mold electromagnetic stirring in continuous casting

IEEE Transactions on Industry Applications, 2001
To get the optimal operation of in-mold electromagnetic stirring through the fundamental characteristics, a three-dimensional magnetohydrodynamic calculation model was used, taking into consideration heat transfer and solidification as well as free surface. Comparison between measured velocity and calculated velocity is in agreement.

Friction-stir welding of cast aluminum alloys

Electrical Metallurgy
The study results of the mechanical properties and structure of cast aluminum alloy joints made by friction-stir welding (FSW) are presented. The processes of intense plastic deformation in FSW have influence on the formation of the microstructure of a weld seam, on which its strength properties depend, however, the determining factor is the ...
