다국어 초록 (Multilingual Abstract)
The deformation behavior of a mechanical alloyed Al-Fe and Al-Fe-Ce alloy was studied in the temperature range of 300℃ to 500℃.
The steady state for Al-8wt.%Fe powder was obtained after 1000 minutes of mechanical alloying at the process condition of 2wt.% stearic acid, 46:1 of grinding media/powder weight ratio, and 300 rpm of impeller revolving velocity. The relative densities of Al-8wt.%Fe alloy powders reached almost 100% after 1 hour sintering at 470℃ under vacuum state. With increasing the amount of PCA, hardness of the sintered alloys increased but the relative densities were not affected. It was also found that decrease in hardness and tensile strength after high temperature aging treatment was reduced with increasing the amount of Ce addition.
