Stress Corrosion Cracking of Amorphous Iron Base Alloys
The stress corrosion cracking behaviour at room temperature of amorphous Fe-Cr-Ni-P-C alloys subjected to constant strain rates was studied in some acidic solutions containing Cl- ions. Hydrogen embrittlement of the alloys occurred in the potential region lower than -300 mV relative to the corrosion potential in acidic solutions regardless of Cl- concentration. In the passive potential region no embrittlement was observed during tests in neutral NaCl solutions and in acidic solutions with low concentrations of Cl- ions. Only when tensile stress was applied to the specimen in relatively strong acidic solutions containing a certain amount of Cl- ions, fracture stress decreased in this potential region. The lowering of the fracture stress can also be attributed to hydrogen embrittlement.
