σ-phase precipitation in weld metal of austenitic stainless steels and its effect on properties

σ-phase precipitation in weld metal of austenitic stainless steels and its effect on properties

Low-temperature conditions necessitate high toughness in the welded joints of austenitic stainless steel structures. However, the impact toughness of the weld metal decreases significantly when using electrodes developed for SMAW under such conditions. To address this issue, a comparative study was...
