In the hot metal forming processes, materials deform viscoplastically and the microstructure of materials changes dynamically, and constitutive equations used to characterize the material flow and microstructure evolution during the deformation can be complicated. Although different types of constitutive equations have been proposed by many researc…

ITER In-Vessel Components (IVCs) will have limited lifetimes and need to be maintained and/or replaced during the operational life of ITER. IVCs are attached to the plant cooling water system via pipework to enable active cooling of the components during plasma operations. When maintenance is required, Remote Handling Systems (RHS) will be used …

Understanding the effects of interfacial micro-structures/-defects such as voids, grain boundaries (GB) and partial recrystallization (Rx) is critical to achieving superior mechanical properties for safety-critical parts. These features may appear during advanced manufacturing processes such as sintering, additive manufacturing (AM), and diffusi…

The International Thermonuclear Experimental Reactor (ITER) is an international nuclear fusion research and engineering project with the aim to prove the feasibility of nuclear fusion as a large-scale carbon-free source of energy. The reactor vessel contains several diagnostic windows that provide a line of sight to the plasma. Design and qualif…

Stainless-steel 316L is one of the widely used structural materials in the nuclear industry, because of its excellent corrosion resistance and mechanical properties. However, very few researches can be found on its viscoplastic behavior and microstructure evolution at warm and hot deformation conditions, which hinder the possible applicat…

The United Kingdom Atomic Energy Authority are involved in the design and manufacture of the diagnostic windows for ITER. ITER is an international project, with 35 nations collaborating to design, construct and operate a prototype controlled nuclear fusion reactor in southern France. As well as providing line of sight for diagnostics, the window…

Internal flow behaviour during melt-pool-based metal manufacturing remains unclear and hinders progression to process optimisation. In this contribution, we present direct time-resolved imaging of melt pool flow dynamics from a high-energy synchrotron radiation experiment. We track internal flow streams during arc welding of steel and measure insta…
