Tailoring of the microstructure and properties of magnesium casting alloys for the application at elevated temperatures

Aim of project
The aim of the project is to examine how the parameters of hot-chamber pressure casting affect the microstructure and mechanical properties of the AE44 and AJ62 magnesium alloys measured at room temperature and at a temperature of 175°C. The examinations included an estimation of porosity of cast alloys, an analysis of their microstructure, and the determination of their mechanical properties at room temperature and at elevated temperatures.

Expected results
Development of new magnesium alloys containing alloying additions (rare-earth elements) to improve creep resistance and insignificantly reduce their castability;

Optimization of die casting parameters to obtain good elevated- temperature mechanical properties due to low casting porosity.
