抄録
The ambient temperature effect on mechanical alloying was studied using a mixture of copper and tantalum powders at a composition ratio Ta:Cu=7:3. This system is characterized by a positive heat of mixing of 2kJ/mol. We confirmed that the higher the ambient temperature during milling, the faster the amorphization proceeds. This thermally assisted amorphization(TAA) becomes noticeable after 60 hours of milling. In addition, we found the evidence for the TAA by annealing a partially amorphized MA powders at temperatures below the crystallization temperature. These results were discussed in terms of thermodynamics.
