Refining of AZ91 Magnesium Alloy Obtained in Machining Chips Recycling.

In the last years the interest in the recycling and re-use of magnesium alloys was increased. AZ91 magnesium alloy is the most widely applied. Recycled magnesium alloys have different disadvantages for your re-use. This paper presents results obtained in the refining of AZ91 alloy, previously obtained in recycling of machining chips. The percentage recovery of refined process is 90%. Fluxes used permit a partial refined, since the microstructures presents a notable decrease of inclusions and porosities, but the chemical compositions of refined alloys does not match with the standard values.
