In order to prepare a bulk amorphous alloy, Al-based amorphous powder was sintered. Mechanical alloyed Al<SUB>70</SUB>Ti<SUB>12</SUB>Si<SUB>18</SUB> powder was used. The powder structure included amorphous and nano-crystalline phases. This powder was milled with Sn, with lower melting point, by mechanical alloying for 36ks. The amorphous powder was coated with Sn by mechanical alloying. This milled powder was sintered by spark plasma sintering in the temperature over the melting point of Sn, but under the crystallization temperature of Al<SUB>70</SUB>Ti<SUB>12</SUB>Si<SUB>18</SUB> powder. A disk specimen of 10mm diameter and 2mm thickness was prepared. The disk specimen of the amorphous alloy was prepared at sintering temperature of 503K and holding time of 1.2ks at 375MPa. The specimen consisted of amorphous phase, crystallized phase and the remained Sn phase. The amorphous phase crystallized at sintering temperature of 533K.
