WebJul 22, 2024 · 27.2: Cooling Curves. The method that is used to map the phase boundaries on a phase diagram is to measure the rate of cooling for a sample of known composition. The rate of cooling will change as the sample (or some portion of it) begins to undergo a phase change. These “breaks” will appear as changes in slope in the temperature-time … WebWith regard to the type of solidification, it can be seen two deviations in the cooling curves of 3.7 and 4.8 wt.% alloys which indicates that phase transformation is occured during solidification
