Six phase changes in the fluid inclusions were recorded during cooling/heating routines: (1) CO2 melting temperature ([T.sub.mCO2]), (2) eutectic temperature
([T.sub.e]), (3) final ice melting temperature ([T.sub.mIce]), (4) clathrates melting temperature ([T.sub.mClath]), (5) C[O.sub.2] homogenization temperature ([T.sub.hCO2]) and (6) total homogenization temperature ([T.sub.h]).
While the concept of "excess manganese" suggests that manganese can completely tie up sulfur prior to the solidification of the melt, thermodynamic calculations show that the reaction manganese + sulfur--MnS is weak and does not go to completion before the metal reaches the eutectic temperature
(typically around 2,150F), see Figure 1.
(2) depression in the (Al-Si) eutectic temperature
in D0 alloys (approximately 16[degrees]C),
The glassy phase was formed by eutectic reaction between [Ta.sub.2][O.sub.5] and Zr[O.sub.2] at the sintering temperature of 1900[degrees]C, because eutectic temperature
is less than 1887[degrees]C in the [Ta.sub.2][O.sub.5]-Zr[O.sub.2] system.
When the shell materials from opposing sides come into contact, which together form an alloy with a eutectic temperature
at or below room temperature, a liquid alloy is quickly formed.
Aluminum-induced crystallization (AIC) induces the crystallization of a-Si below the eutectic temperature
(577[degrees]C) of Al and Si.
There were 8 input parameters: liquidus temperature, [T.sub.liq], lowest eutectic temperature
, [T.sub.e,low], the recalescence, R, solidus temperature, Ts, graphite factor 1, GF1, graphite factor 2, GF2, cooling rate at solidus, d[T.sub.s]/dt, and eutectoid temperature, [T.sub.eid].
This low temperature can be achieved since the eutectic temperature
of the proposed blend with oil shale is low.
The ternary eutectic temperature
for SnAgCu is 217[degrees]C, but the joint does not have to reach this temperature for the overall solder to melt when SnPb eutectic and SnAgCu alloys are mixed.
Due to the absence of lead, the eutectic temperature
is now higher, around 215[degrees]C.
When the path intersects the face and the edge, the 11 9 x 5 phase and CuO also crystallize, and eventually at the 2212 eutectic temperature
, 2110 also appears.
