In this study, a bulk Mg65Cu25Y10 deposit was produced successfullyvia spray forming process with higher cooling rate than conventional mold castingroute. 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 looksimilar 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. Thehardness of the deposit is higher than that of melt spun ribbons. The supercooledliquid region of the deposit determined from TMA technique is about 20K smaller thanthat obtained from DSC trace due to the stress induced nanocrystallzation occurredin the former. In addition, the volume reduction of deposit during TMA test was alsosmaller than that of ribbon and shows better dimension stability.
