As common in such systems, there is a certain composition called the eutectic composition (here with 60% Sn), at which the liquid phase has a lowest freezing point.
And the DSC plot showed that the melting point of 99.02[degrees]C and the latent heat of the quaternary eutectic composition was 174.71 J/g.
A review of the phase diagram showed a promising eutectic composition at approximately 10 wt% cerium that suggested the alloy could be cast.
When the eutectic composition is reached, carbon precipitates as graphite and the eutectic solidification starts.
% of Al, which is an alloy of nearly eutectic composition, its strength is highest.
The lowest temperature of the liquid phase is detected at the eutectic composition. Therefore additional graphite of the crucible does not cause a further decrease of the freezing temperature.
Assume that a given SAC solder volume has the exact ternary eutectic composition Sn3.5Ag0.9Cu.
In the works, carried out within the last years, materials Ti-Al-Si, produced by two methods-directed solidification of alloys Ti-Si for the purpose of formation in the matrix a-Ti of fibers [Ti.sub.5][Si.sub.3] and production of fine-grain structures of pre-eutectic or eutectic composition, representing a-Ti matrix with particles [Ti.sub.5][Si.sub.3], having size of several microns, were investigated [10-12].
Because of this, temperature range for growth of primary dendrites is lower with higher Si contents and therefore the SDAS is smaller, but in the microstructure more particles of Si with eutectic composition will be found.
