Abstract
ABSTRACT
Mg-based amorphous alloys exhibit maximum specific strength among bulk metallic
glass systems. In this study, a bulk Mg65Cu25Y10 deposit was produced successfully
via spray forming process with higher cooling rate than conventional mold casting
route. The deposit is 300mm in diameter, 10 mm in thickness and 650 g in weight.
The average porosity is about 10%. The XRD and DSC results of the deposit look
similar to that obtained from corresponding amorphous melt-spun ribbon. However,
the measured composition of deposit varies slightly with the distance from substrate,
which attribute to gravity effect of relative heavy element, like Y and Cu. The
hardness of the deposit is higher than that of melt spun ribbons. The supercooled
liquid region of the deposit determined from TMA technique is about 20K smaller than
that obtained from DSC trace due to the stress induced nanocrystallzation occurred
in the former. In addition, the volume reduction of deposit during TMA test was also
smaller than that of ribbon and shows better dimension stability.
