• Effect of ball milling on structure and thermal stability

    The influence of ball milling on microstructure and thermal stability of the gas-atomized Al 84 Gd 6 Ni 7 Co 3 glassy powder has been investigated as a function of the milling time. The results show that the traces of crystalline phases present in the as-atomized powder decrease gradually with increasing the milling.
