Secondary phases in Al-Si piston alloy

  • vsundar


    3-D images of the secondary phases were obtained using the Robo-Met.3D system.   High contiguities between Si, aluminides and Mg2Si were observed in both alloys without and with UST.  Mg2Si phase were observed mainly adjacent to the eutectic platelets of Si or aluminides.
