摘要：

The low atomic mobility in metallic glasses such as amorphous aluminium alloys permits the isothermal study of heterogeneous nucleation. The action of conventional grain-refining additions containing Al3Ti and TiB2 has been investigated microscopically in a devitrification study of Al85Y8Ni5Co2. Particles of TiB2 with a thin coating of Al3Ti are the nucleating agent; copious nucleation of alpha-Al occurs on the (001) faces of these particles.
