Integration of advanced experiments, computation and data for Duplex Stainless Steel joininginnovation

Welding and joining of advanced alloys such as Stainless steels (SS) and related systems are one of the most important R&I areas directly relevant to economies, health, and environments. Advanced grade Duplex stainless steel (DSS) with a mixed ferrite-austenite (+) structure, has superior mechanical and corrosion resistance with increased applications in many industries. The complex alloying system naturally results in complicated microstructural zones, phases and properties, which are difficult to control and predict during welding, joining and related processes due to the thermal-mechanical-physical processes. The issues become more challenging for situations such as multi-pass welding, hybrid structures and dissimilar materials. This is a critical issue affecting the development of data-led R&I, wider applications and management of the materials as well as the development of more efficient manufacturing/production processes. The overall objective of the project is to develop systematic collaborative advanced research on the key controlling structures, phases and properties with integrated experiments and modelling. This will enhance the combined functional performances, applications, materials design and manufacturing techniques. It will contribute to the current global effort in knowledge based digital manufacturing by tackling the critical scientific issues. The scientific objectives have been achieved through 7 collaborative work packages following a dynamic mechanism. The main technical works in the project have been focused on developing an in-depth understanding and data of compositions, microstructure, phase ratio (e.g. ferrite/austenite, precipitations) of the fusion zones and heat affected zones; the key controlling factors and mechanisms of surface treatment and corrosion resistance; the development of CAE system with advanced data; establishing the effects of composition, defects and other parameters (e.g. temperature) on the fundamental physical and interface parameters through physical modelling; research on welding and joining of dissimilar/hybrid materials and data systems development.

Project objective

The proposed project aims to collaboratively research on welding of duplex stainless steel (DSS) through modern data system/sharing, experiments and predictive physical modelling for developing new materials and processing regimes. The project will establish a systematic data system for the key physical structure/phases relative to the welding and corrosion of DSS. The project will establish the optimum welding regimes for enhanced mechanical and corrosion performance with the aids of hybrid computer aid design and manufacturing (CAD/CAM) and physical based material modelling. The data and advanced approach will be used to develop new disruptive manufacturing technology to control the structure, phase and defects in the welding in particularly the heat affected zones (HAZ), which is the most critical/limiting issue for manufacturing and applications of DSS and other material systems. The work will jointly explore the use of modern data and predictive modelling technology in developing dissimilar/hybrid material systems for more significant weight/cost reduction. The resulted advanced data system, new materials, welding process and hybrid lightweight materials will contribute the research and innovation capacity in Europe and the world on DSS, stainless steels and associated systems with a long term economic and social impact (e.g. health, environments and society). The advanced data system will serve as a pivoting platform for future research and innovation, speeding up material or product development cycle, with fundamental contribution to academic and industrial R&D. It will enhance the R&I capacity of inter/multidisciplinary intersectoral partners, and jointly developing major break-through technologies. The work combined several novel approaches I R&D, will contribute the development of Industry 4.0 for welding and significantly accelerate the development of the Research skills, knowledge and career of the ECR with lasting impact in the EU and beyond.
