Internal reversible hydrogen embrittlement leads to engineering failure of cold drawn wire

(in lingua inglese)

On the basis of the above experiments, it was determined that the failure had occurred due to the hydrogen embrittlement. Itis likely thatthe hydrogen came from the HCl solution atthe stage of pickling operation and the subsequent baking was not carried out properly. That led to the retention of hydrogen atom in the interface and during the drawing operations failure resulted. Therefore, minimizing of the pickling operation time and proper baking should prevent this type of industrial failure.
