摘要：

In the present research, intergranular precipitation and corrosion in the weld of low Cr ferritic stainless steel was investigated. Free-exposure and double loop electrochemical potentiokinetic reactivation corrosion test results revealed that IGC occurred in both the weld metal and heat-affected zone of the welds aged for more than 1 h at 500 A degrees C. Intergranular Cr segregation was observed around the TiC precipitation of the weld in which IGC developed during the corrosion tests. This observation is subsequently discussed in the experimental results.
