(2) The changes in both [alpha]-Al and Si eutectic temperatures are independent of the undercooling.
Figure 2 shows the parameters taken from thermal analysis cooling curves for characterizing the (Al)-Si eutectic arrest which, according to the authors, comprises the minimum eutectic temperature ([T.sub.e,min]), maximum eutectic temperature (Te>max), and recalescence (ATe).
This reduction of energy is believed to occur as a result of formation of low eutectic temperatures when using oil shale.
This low temperature can be achieved since the eutectic temperature of the proposed blend with oil shale is low.
Test the inoculated iron, and plot your results as a cooling curve, recording eutectic temperatures [ILLUSTRATION FOR FIGURE 1 OMITTED]).
Both maximum and minimum eutectic temperatures should be as high as possible, and the maximum recalescence rate should be reduced.
The activity of carbon in liquid iron is insufficient to react with slag--only in extremely fluid conditions can slag be brought into intimate contact with graphite at eutectic temperatures. The MgS dissolves in the FeSi/MgSi slag, lowering its melting temperature, thereby enabling the slag to remain fluid enough to react with graphite at these temperatures and produce CO.
The Al-Si eutectic temperature for each thermal analysis sample was defined as the maximum temperature observed during the Al-Si eutectic arrest on the cooling curve.
Recently, the Sn-9Zn alloy system has received increased interest since it features low cost, great mechanical properties, and a low eutectic temperature (198[degrees]C), close to that of the Sn-Pb alloy [2, 3].
At Sr/Bi ratios (by weight) below 0.2, the Si structure was unmodified and the eutectic temperature remained between 1048-1055F (564-568C).
Solidification is complete when the temperature again decreases, dropping the curve below the eutectic temperature.
