It is a liquid state composite material fabrication method during which a dispersed particles like ceramic particles, short fibers are mixed with a molten matrix metal by means that of mechanical stirring.
Among the variety of manufacturing processes available for discontinuous metal matrix composites.
In general the metal matrix composites of stir casting involves production of molten metal of selected matrix material followed by reinforcing material in to the molten metal.
Solidification containing suspended particles to get the required distribution of the dispersed particles.
Particle distribution changes considerably depending on method parameters throughout the melting and solidification stages of the method.
The addition of particles to the melt drastically changes the viscousness of the molten metal.
It is vital that solidification occurs before appreciable settling is allowed to take place.
ADVANTAGES :
Simple, flexible and used to large scale production.
Sustain high productivity.
Cheaper 1/3 to ½ than the other methods.
