抄録

In order to fabricate the aluminium based composite materials exhibiting phosphorescence properties, aluminium powder and phosphorescence powder (LG) were mechanically alloyed (MAed) using a vibrational ball mill, and the MAed composite powders were consolidated into bulk materials by spark plasma sintering (SPS). Changes in hardness, constituent phases, powder particle sizes and luminance of both the MAed powders and SPS materials were examined by a hardness tester, X-ray diffraction, scanning electron microscopy and luminance meter, respectively. The Vickers microhardness of the MAed powders increased both an increase in MA time and the amount of LG powder addition. No solid-state reactions could be detected in the MAed powders. The mean particle size of the MAed powders for 60 min was smaller than that for 5 min. The Vickers hardness of the bulk SPS materials increased both an increase in MA time and the amount of LG powder addition. SPS materials showed luminance properties in a darkroom after they were irradiated under black light. The optimum process conditions for MA time was 5 min and for the sintering temperature was 873 K.
