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.

Magnetic Stirring in Horizontal Continuous Casting

2001
For the horizontal continuous casting process, the flow field, the temperature distribution and the formation of the shell are analysed by means of a finite-element solution of the Navier-Stokes and the energy equations for axisymmetric laminar flow.

Electromagnetic stirring for continuous casting - Part 2

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.

Friction Stir Welding of Magnesium Die Castings

2016
Friction stir welding (FSW), being a solid-state process, is an attractive method for joining magnesium die castings. In this study, FSW of AZ91D and AM50A plates was performed both on the individual alloys and to join them together. The welds were sound and free from defects, except for small surface cracks in AM50A; a fine microstructure ...

Casting Optimization Study on Fe/Al In-situ Composites Synthesized by Stirring Casting

2011 Third International Conference on Measuring Technology and Mechatronics Automation, 2011
Through analyzing the reaction kinetics of Al-Fe reaction and the growing factors of strengthening phase crystals, we find that reducing the initial size of Fe powder dumpling added into liquid Al melt and strengthening agitation to the Al-Fe mixed melt can accelerate reaction and refine strengthening phase grains and Al matrix crystals to gain the ...

Fabrication and Characterization of Cast Magnesium Matrix Composites by Vacuum Stir Casting Process

Journal of Materials Engineering and Performance, 2003
A vacuum stir casting process is developed to produce SiCp reinforced cast magnesium matrix composites. This process can eliminate the entrapment of external gas onto melt and oxidation of magnesium during stirring synthesis. Two composites with Mg-Al9Zn and Mg-Zn5Zr alloys as matrices and 15 vol.% SiC particles as reinforcement are obtained.
