ABSTRACT

The composite in Al matrix are the alloys with some refining elements like Ti, B, Sr,
etc. need to know all the techniques used for refining the structure.
That is why we describe the three techniques including the rapid cooling of the melting,
the mechanical, the electromagnetic or the ultrasonically stirring of the melting and the
adding of the sells or the pre-alloys in the melting.

Keywords: al matrix composite, refining, structure, finishing techniques
