However, thick-plate submerged arc welding (SAW) can introduce elevated hydrogen levels and residual stresses that promote time-delayed hydrogen-assisted cold cracking (HACC). Accurate, microstructure-specific diffusion data are scarce, limiting predictive HACC assessments. This study presents an experimental determination of hydrogen diffusion coefficients (<i>D</i><sub>H</sub>) in two S690 variants: thermomechanically rolled (S690MC) and quenched and tempered (S690Q). Multi-layer SAW welds were produced from 30-mm-thick plate material at three heat input levels, and diffusion membranes were extracted from weld metal (WM), heat-affected zone (HAZ), and base material (BM). Hydrogen permeation tests, conducted in accordance with DIN En ISO 17081, yielded flux curves normalized in time from which <i>D</i><sub>H</sub> was derived using the inflection-point method. At room temperature, <i>D</i><sub>H</sub> values ranged from 6 × 10<sup>−5</sup> mm<sup>2</sup>/s to 9 × 10<sup>−5</sup> mm<sup>2</sup>/s across all regions and heat inputs, with no significant difference between S690MC and S690Q. Weld metal exhibited marginally lower <i>D</i><sub>H</sub>, attributed to enhanced hydrogen trapping, while base material measurements showed greater variability. These microstructure-resolved diffusion coefficients add quantitative data for modern S690 SAW welds and provide internally consistent input parameters for the numerical simulations presented in part 2. The results support improved parameterization for subsequent assessments of HACC risk through the optimization of welding parameters.</p></div>","PeriodicalId":809,"journal":{"name":"Welding in the World","volume":"70 11","pages":"5353 - 5367"},"PeriodicalIF":3.1,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40194-026-02400-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AM offers economic advantages and enables an efficient use of materials. However, AM components often require subsequent mechanical post-processing, such as machining (e.g., milling), to achieve the final contours or surfaces. This is a particular challenge due to the heterogeneous and anisotropic nature of AM structures, which affect machining and the resulting component properties. High-performance materials such as iron aluminide represent a promising alternative to conventional high-temperature materials with a significant economic advantage. However, the strength and hardness properties, which are advantageous for applications in highly stressed lightweight components, pose a challenge for economical machining in addition to the AM microstructure properties. The difficult-to-cut material causes accelerated tool wear and insufficient surface quality. This study shows that crack-free additive manufacturing of the three-component system of iron-nickel-aluminum is possible, and advantages in terms of machinability compared to FeAl-AM components are achieved. The more homogeneous microstructure leads to a reduction in cutting forces, with positive effects on the machinability and optimized surface integrity. Ultrasonic assisted milling (USAM) offers great potential to address the major challenges posed by difficult-to-cut materials and additively manufactured weld structures. Therefore, this study focuses on assessing the transferability of previous positive results by USAM to the selected iron aluminide alloys.

Heat-affected zone softening, which leads to localized loss of strength and hardness, is a significant issue in welded aluminum components. This issue prevents the welded components from achieving their full load capacity, leading to premature failure in their heat-affected zone, despite acceptable weld quality. Accordingly, this study investigates the failure mechanisms of the heat-affected zone in non-heat-treatable 5754-H22 and heat-treatable 6082-T6 aluminum alloys. Samples are welded with different welding processes and heat inputs to clarify the influence of the welding procedure on the failure mechanism. Microstructural analyses, simulated thermal gradients using finite element, CALPHAD, and strength analytical approaches were employed to investigate the softening phenomenon. According to the results, the softening in the non-heat-treatable base metal was mainly due to dislocation recovery, while precipitation coarsening caused softening in the heat-treatable base metal. Tensile tests conducted in conjunction with digital image correlation revealed that the mechanical behavior of the welded joints followed that of their softened heat-affected zone. Furthermore, hardness-strength and stress-plastic strain empirical models were capable of predicting the deformation behavior of softened heat-affected zones, and thus, welded aluminum structures. However, the model parameters need to be adjusted for each specific base metal. Finally, autogenous laser welding showed reduced softening. However, it led to undercut defects and premature failure due to the absence of filler material, suggesting that using filler material in laser welding could be a viable solution to reduce softening in aluminum alloys.</p></div>","PeriodicalId":809,"journal":{"name":"Welding in the World","volume":"70 11","pages":"5331 - 5351"},"PeriodicalIF":3.1,"publicationDate":"2026-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40194-026-02394-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, while PWHT can reduce residual stress, it may also increase or decrease welding deformation depending on the applied process, thereby affecting fatigue life.

Nitrogen loss, as can occur during welding, delayed austenite formation and shifted phase stability, especially in lower-alloyed DSSs. The onset of Cr<sub>2</sub>N nitride precipitation was closely tied to insufficient austenite formation, with the critical austenite fraction varying by alloy composition and cell size.
