摘要：

The influence of structural changes such as structural relaxation and crystallization on the corrosion resistance of the amorphous Fe74Cu1Nb3Si13.5B8.5 alloy in 0.1M sulphuric acid was investigated. A controlled crystallization of such amorphous alloy leads to nanocrystalline microstructure which increases the corrosion resistance, whereas structural relaxation of amorphous alloy results in reduced corrosion resistance. Different conditions of relaxation (330 degrees C and 380 degrees C) and structural crystallization (554 degrees C and 610 degrees C) were analyzed. (C) 1999 Elsevier Science B.V.
