CHARACTERIZING SOLIDIFICATION BY NON-EQUILIBRIUM THERMAL ANALYSIS

摘要

Research and development of Mg alloys depends on the metallurgist's understanding of and ability to control microstructures. In this research, equipment for non-equilibrium thermal analysis of Mg alloys has been created and tested using AZ91E. AZ91E was selected as a test case since it is among the most widely used and understood Mg alloys. Results from thermal analysis demonstrate the equipment's sensitivity and the technique's ability to detect many of the salient features of solidification. These results correlate well with existing data. Relative to other research equipment required for studying microstructural evolutions this non-equilibrium thermal analysis equipment is rapid, inexpensive, easy to maintain and operate, and surprisingly sensitive. Therefore, it should prove to be a valuable research tool for those people interested in Mg alloy development.
