Influence of Natural Ageing on Precipitation Processes during Isochronal Annealing in MgGd alloys
Original language description
The Mg-10 wt. % Gd and Mg-15 wt. % Gd alloys produced by squeeze casting were solution treated at 500 oC for 8 hours and subsequently naturally aged for more than 2 months. Electrical resistivity of both materials measured at 77 K decreases, if the alloys are kept at room temperature after quenching from the solution temperature. This change accompanied by a microhardness increase almost saturates after 2 months and is caused most probably by solute atoms clustering. Phase transformations and microhardness changes were investigated during isochronal annealing in both naturally aged alloys in comparison to just solution treated ones. Electrical resistivity changes measured at 77 K were used to characterize microstructure development. Transmission electron microscopy was performed at selected states heat treated in the identical way. The Mg15Gd supersaturated solid solution isochronally annealed up to 500 oC immediately after the solution treatment decomposes into following successive ph
