Cr type steel Electrochemical technique Key Words Laves phase Peak of current density Toughness
The weld metal of modified 9Cr-1 Mo steels is most low toughness in its MIG weld joint. It is necessary to pay attention to the toughness of weld metal because of securing to ughness of weld joint. The weld metal of precipitated Laves phase after long-term thermal aging decreased toughness. Peak of the current density (Ip) in the electrochemical t echnique was appeared in the weld metals of precipitated a lot of large Laves phase. It seemed that appearance of lp was caused by the dissolution of the Lave...
