“…A comparison of reference temperatures predicted with equations from the present work, Apelian et al [2], Stuhldreier et al [12] and Djurdjevic [14], with thermal analysis data from literature [2,[14][15][16][17][18][19][20][21][22][23][24][25] is shown in Figure 3a. In addition, comparison with calculations made with Thermo-Calc and the TCAL1 database [26] according to Scheil's model are also shown in Fig.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract. The modification level of Al-Si alloys is generally evaluated by the depression of the (Al)-Si eutectic temperature which can be recorded by thermal analysis. However, this method requires a reference temperature which should be the eutectic temperature evaluated on the relevant phase diagram. Various methods proposed to account for the effect of low level alloying elements on this reference temperature are reviewed and emphasis is put on the so-called "Mondolfo's equation" which is updated. Predictions are compared to experimental information from literature.

“…This more likely indicates that the exact temperature for the onset of the Al 2 Cu phase depends mainly on the amount of Cu in the molten metal, which is constant in all treated alloys in the present study. It has been reported that the precipitation temperatures of Cuenriched phases decrease when Cu increases from 1 to 4 mass% in an AlSi5Cu system [27].…”

The influence of grain refinement-with the addition of 6 mass% Al-5Ti-B and 10 mass% Al-3Ti-B master alloys-on the temperature-based parameters of a commercial ADC12 die-casting alloy, modified with 0.04 mass% Sr, was investigated using computer-aided cooling curve thermal analysis. Results show that the addition of grain refiners caused the reaction area of the aluminium dendrite to shift up. With the addition of refiner reagents, the nucleation temperature and growth temperature for the evolution of the primary Al dendrite increased, while the recalescence temperature decreased. The dendrite coherency temperature (T DCP ), time (t DCP ), temperature (T N -T DCP ), and time (t N -t DCP ) interval for dendrite coherency and solid fraction at coherency point increased with the addition of Al-3Ti-B and Al-5Ti-B grain refiners. Nevertheless, the growth temperature of the eutectic aluminium-silicon phase remained at the modified range (563.5-565°C) even after the addition of grain refiners. A grain-refined and modified structure was obtained after the addition of refiners, but no obvious mutual effect was found in terms of the coarsening of grain size or silicon demodification in the range of concentrations used in this study.

“…Small test samples and rapid cooling rates minimize structural transformation during quenching and thus maximize the accuracy of this measurement procedure. Another approach for determining fraction solid makes use of the TA technique [3,4,17,25,26,[28][29][30][43][44][45][46][47][48][49][50][51][52]. The amount of heat evolved from a solidifying test sample can be calculated as the integrated area between the first derivative curve and the zero line.…”

“…All of these characteristic solidification temperatures, as Figure 2 illustrates, can be easily determined using the thermal analysis (TA) technique [12]. The TA has been used for many years in aluminum casting plants as a quality control tool [3,4,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. There are many reasons why this more than hundreds of years old technique has commercially applied at numerous aluminum foundry plants.…”

This chapter presents the potential of the cooling curve analysis to characterize the solidification path of the cast hypoeutectic series of Al-Si-Cu alloys and to quantify their feeding regions. The aim of this work is to examine how variations in the chemical composition of Si (5, 7 and 9 wt.%) and Cu (from 0 to 4 wt.%) might affect the characteristic solidification temperatures, their corresponding fraction solid, and feeding regions of investigated alloys. These parameters collected from the cooling curve analysis can be used for better understanding of the solidification paths of Al-Si-Cu alloys and could easily be incorporated into existing simulation software packages to improve their accuracy.
