Comparing conventional metals, the preparation condition of non-crystaline amorphous metal is more harsh, in order to prevent the crystallization in material preparation process, it is necessary to: 1) in protective atmosphere system or melting under high vacuum condition.2) there is sufficiently high cooldown rate, for the Zr about 1K/s of base noncrystal alloy cooldown rate.
Therefore, tradition is prepared the method for foam metal and is difficult to directly apply to amorphous.At present, have attempted to successful method mainly have:
(1) foaming agent method, it is only limited to Pd (noble metal) base amorphous, thus it is difficult to that there is practical value, this is owing to foaming agent principle conventional at present is that hydride decomposes goes out hydrogen so that material foams, and the non-crystaline amorphous metal of most of system is easy to make mechanical properties decrease due to hydrogenation.
(2) THROUGH METHOD, generally together heats amorphous and dissolved salt and together cools down, very easily cause Amorphous Crystallization due to rate of cooling not, and the amorphous foam mechanical property thus prepared is even not as traditional foam aluminium alloy.
In order to make up the deficiency of existing technology of preparing, and successfully prepare the non-crystaline amorphous metal foamed materials of excellent performance, it is necessary to existing non-crystaline amorphous metal preparation facilities is improved.
