Utilizing the electropulsing assisted solution (EAS) treatment, we prepared ultra-high strength steel with increased strength and plasticity at lower temperatures and in drastically reduced timeframes. The multiple strengthening mechanisms and the plasticizing mechanisms associated with multiscale microstructures are systematically discussed. Comparisons indicate that the strength and plasticity of steels treated with EAS surpass those of steels subjected to optimize conventional furnace solution treatment. Specifically, the experimental steel subjected to electropulsing assisted solution at 850 °C for 45 min showcased a maximum tensile strength of 1924.5 MPa. This impressive feat is credited to a high dislocation strengthening of 582.3 MPa and a grain refinement strengthening of 159.7 MPa. Additionally, a peak elongation-to-failure of approximately 14.2% was observed in EAS at 885 °C for 30 min. This improvement can be attributed to the activation of the slip system, coupled with an increase in the high-angle grain boundaries fraction numbers. These changes, in turn, amplify the coordinated deformation capacity, minimizing crack propagation.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 2","pages":"339 - 354"},"PeriodicalIF":3.3,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141938824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its cost-effectiveness and high deposition rates make it suitable for creating substantial and complex parts. However, the mechanical and microstructural properties of these components can be influenced by the varying heat input and repeated thermal treatments associated with different welding procedures used during the deposition process. This study employed gas metal arc welding (GMAW) and cold metal transfer (CMT) arc welding techniques to fabricate cylindrical components from 2209 duplex stainless steel (DSS). The research investigated the impact of these welding methods on the microstructure and mechanical properties of the 2209 DSS cylinders. The intricate thermal cycles and cooling rates inherent in the DED process significantly influenced the primary phase balance, ideally comprising 50% austenite and 50% ferrite. In components processed using GMW, σ-phase formation was noted at the grain boundaries. Additionally, a slower cooling rate and extended time for solid-state phase transformations led to an increase in austenite content from the bottom to the top of the component. The cylinder fabricated using the CMT process exhibited fine austenite morphologies and a higher ferrite content compared to the GMW-processed cylinder. Furthermore, the cylinder produced using the CMT process showed consistent properties across the building direction, unlike the components manufactured with the GMW process. In terms of tensile properties, hardness, and impact toughness, the cylinder produced using the CMT technique outperformed the one made with the GMW process.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 2","pages":"368 - 391"},"PeriodicalIF":3.3,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141938825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The manuscript begins with an overview on the principle of operation and classification, and subsequently extends the topic to detailed discussion on the joint characteristics, microstructure, material combination and application domain. The literature on LFW was studied and classified based on similar and dissimilar materials, effects of parameters on properties and microstructure responses, evolution of heat and stress conditions, and applications.

The microstructures are refined with an increasing manganese content in as-built HMS; as a result, hardness decreases. The UNSM treatment enhanced the surface characteristics of the material, reducing weight loss and improving wear resistance, particularly for alloys with a low manganese content. Specifically, the UNSM-treated (UNSMed) 13Mn sample exhibits the highest wear resistance, owing to its high surface hardness, which effectively limits wear damage within the severe plastic deformation (SPD) layer. In contrast, UNSMed 18.5Mn and 24Mn samples, which have lower hardness, experience more severe wear damage that extended beyond the SPD layer. Transformation-induced plasticity and twinning-induced plasticity effects are also observed in all wear test samples, along with increased dislocation density near the surface.
