Solidification curves for commercial Mg alloys obtained from heat-transfer modeled DTA experiments

摘要: Abstract An improved method is presented for determination of solidification curves, i.e., solid fraction versus temperature, commercial Mg alloys using heat-transfer modeled differential thermal analysis (DTA) curves. A better simulation the measured DTA signal attained through an independent measurement time constant as function temperature applied equipment. This enables a desmearing signal. Challenging could be appropriately handled by redesigning tantalum encapsulation. Due to high oxygen affinity and vapor pressure investigated magnesium alloys, this special adaptation setup sealed Ta capsules was indispensable generation reproducible reliable data.
