摘要：
The precipitation sequence in two commercial magnesium alloys, WE43 and WE54, are described. The technique of in-situ thin foil microanalysis has been used to determine the composition of the transition phases formed in WE54. A loss of ductility of both alloys, initially in the T6 condition (solution treated, quenched and aged for 16h at 250 degrees C), during extended exposure to temperatures as low as 100 degrees C is shown to be associated with the precipitation of G.P. zones and the intermediate phase beta " within the microstructure developed by the initial T6 treatment.
