... corrosion. In addition, the density of inclusions in the heat-affected zone (HAZ) was high and the average size of inclusions was larger, resulting in poorer pitting resistance in the HAZ. And pitting was more likely to occur and subsequently a large pit was developed which ultimately led to failure...

...Jun Xiao; Ting Xiao; Guoqing Li; Bing Tang; Yuqi Zheng; Hao Wang; Yong Chen; Shaoyu Qiu Fatigue crack growth (FCG) in Z2CND18-12N austenitic stainless steel and its heat-affected zone (HAZ) in the Z2CND18-12N/16MND5 dissimilar metal weld joint has been investigated in room temperature air and 325°C...

... corrosion and erosion-corrosion performance of the carbon steel parent metal of the pipe work in comparison to the heat-affected zone (HAZ) and the nickel-molybdenum weld material. The program of experiments assessed the potential of two corrosion inhibitors to control adequately the material degradation...

... distributions were created that generally are not present in parent metal AA 7075-T651. Typically, in the weld and heat affected zone (HAZ), the times at peak temperature were short, cooling was relatively rapid, and peak temperatures were < ≈ 500°C. Accordingly, a corresponding microstructural gradient...

... welding, however, iron can precipitate from solid solution onto grain boundaries in the heat-affected zones (HAZ). During seawater service, these iron-rich precipitates can dissolve preferentially (galvanically), leading to intergranular corrosion of the HAZ. The present report described 90-10 Cu-Ni...

...C.-M. Liao The behavior of stress corrosion cracking (SCC) of an overaged Al-3.7wt%Zn-2.5wt%Mg alloy including base metal, weldment, and heat-affected zone (HAZ) in 3.5% NaCI solution was investigated. This Al-Zn-Mg alloy loaded in longitudinal or long transverse direction has good SCC resistance...

...K. Tamaki; K. Yasuda; M. Kimura The corrosion resistances of the girth-weld heat-affected zone (HAZ) of duplex stainless steels were discussed regarding their use in pipeline for hostile environments. A girth-welded HAZ with a slow cooling rate welding procedure and a high-pitting-index base metal...
