CORRELATION BETWEEN MORPHOLOGICAL AND FRACTION SIZE OF INTERMETALLIC ON FLUIDITY OF AL-11%SI ALLOY WITH FE ADDITION
ABSTRACT: Intermetallic
morphology influence on the fluidity of alloys Al-11% Si. From the experiments,
fluidity in the alloy Al-11% Si were added 0.6, 0.8, and 1.0% Fe, it was found
that the higher the Fe content is added to the values decreasing fluidity. On
addition of 1% Fe provides the longest phase of intermetallic 50.2 µm, while
the shortest intermetallic phase is given by the addition of 0.6% Fe 21.3 µm.
In the alloy Al-11% Si with the addition of Fe are generally higher and higher,
would produce intermetallic area fraction increased significantly. On addition
of 0.6% Fe intermetallic area fraction of 1.01%, while the addition of 0.8% and
1% Fe Fe each area fraction 1.16% and 2.26%.
