Abstract

Thixotropic AZ91HP/AM60B Mg alloys have been focused on only in the aspect of semi liquid forming until now. In the present study, with the aim of improving hydrogen storage capacity, we observed the microstructural evolutions and chemical properties of the thixotropic microstructure of AZ91HP/AM60B Mg alloys by using a partial remelting process. According to the results of pressure-composition-isotherm (PCI) measurements and image analysis, globules (the Mg rich solid phase) were regarded as the hydrogen absorbing phases and eutectic/liquid droplets (the quenched liquid phase) were considered as the catalyzer to improve hydrogenation kinetics. Especially, the hydrogenation properties depended on the properties of globules and liquid fractions. The thixotropic AZ91HP Mg alloys (4h crushing under 2MPa hydrogen atmosphere) treated at 863 K and 868K have a liquid fraction of about 50–60% and hydrogen capacity of about 4.5 mass% at 623 K. On the other hand, most of thixotropic AM60B Mg alloys had good hydrogenation properties at above 573 K.
