Comments on experiments
Temperatures were determined on heating. The heating/cooling rate was a maximum of 10 K/min. Some measurements were performed at 5 K/min, and no statistical difference was found between measurement made at 10 K/min and 5 K/min. The solvus temperatures are the average of a minimum of three separate measurements (mixed between 5 K/min and 10 K/min), while the solidus and liquidus temperatures are a single measurement.
