At the eutectic temperature for typical commercial cast iron chemistries, the equilibrium constant, Keq, for the reaction Mn + S--> MnS is around 0.03.
As reported previously by the present authors [3, 17], the observed depression in the eutectic temperature due to addition of RE metals is not necessarily related to modification of the eutectic Si particles as shown in Figure 5.
The relevant thermal parameters were liquidus temperature, lowest eutectic temperature, the recalescence, solidus, graphite factor 1, graphite factor 2, cooling rate at solidus, and eutectoid temperature.
This reduction of energy is believed to occur as a result of formation of low eutectic temperatures when using oil shale.
This ability is dependent upon the percentage of chemical in solution and is expressed as the "eutectic temperature" of the solution.
And the lowest eutectic temperature was 424.05[degrees]C which was in good agreement with experimental results of 424[degrees]C measured by DSC.
If an alloy containing 4.5% copper is poured and held near the eutectic temperature, the casting will be in the single phase field corresponding to solid aluminum.
Furthermore, crystals of tin-copper's intermetallic ([Cu.sub.6][Sn.sub.5]) easily precipitate at its eutectic temperature and the solder itself attacks the copper surfaces of boards it comes in contact with.
The eutectic temperature in the tin-silver-copper system is 217[degrees]C, higher than eutectic tin-lead by 34[degrees]C.
Figure 2 shows the parameters taken from thermal analysis cooling curves for characterizing the (Al)-Si eutectic arrest according to the authors: minimum eutectic temperature ([T.sub.e,min]), maximum eutectic temperature ([T.sub.e,max]), and recalescence ([DELTA][T.sub.e]).
