기계적 합금화에 의한 비정질 Cu55Ti45 분말의 제조 및 성형

Fabrication and consolidation of amorphous Cu55Ti45 powders by mechanical alloying

The Cu55Ti45 system was effectively mechanically-alloyed using a pulverizer. Noncrystallinities of the powders were characterized by TEM, X-ray and DSC. The amorphous powders were consolidated without losing their noncrystallinities. The consolidating conditions keeping a non-crystalline were obtained by building a TTT diagram of the amorphous powders. The microhardness of the crystallite and bulk amorphous alloys are also compared.
