Research topic: Crystal Plasticity Modeling of High-Temperature Creep/Creep-Fatigue Behavior of Nickel-Based AlloysNickel-based Alloys are widely used as structural materials for high-temperature power plant steam generators due to their exceptional combination of high-temperature strength and creep resistance. In addition, the alloys also have excellent resistance to high-temperature corrosion. Under intermediate heat exchangers in the high-temperature reactor, the material undergoes extreme thermal (up to 950°C) and mechanical loadings, including fatigue and creep-fatigue induced by the startup and shutdown cycles. Therefore, prediction of failure and lifetime of this alloy under high-temperature creep-fatigue conditions is of important interest. In order to capture the response in cyclic loading and demonstrate the life prediction capability, a computational model that incorporates the underlying physics of the plastic deformation is investigated at the micro scale. In this work, a crystal plasticity model is developed to idealize the fatigue and creep-fatigue cycles in the high-temperature environment. A dislocation climb mechanism is incorporated in the CPFEM to capture the primary/secondary creep strain. Furthermore, cohesive elements inserted at grain boundaries are investigated to describe a failure process on the polycrystal deformation under creep and creep-fatigue loading conditions at a high temperature.Outline of duties:1. Development of a crystal plasticity model for creep deformation modeling of Nickel-based Alloy Inconel 617 at higher temperatures by incorporating a dislocation climb model.2. Performance of crystal plasticity finite element simulations including cohesive-based failure modeling of the grain boundary cavitation induced by creep phenomenon at high temperature for a better understanding of the limits of candidate materials, which in turn leads to improved safety and performance of next-generation nuclear reactors.

A deep drawing finite element simulation is performed by applying the crystal plasticity model considering experimentally-based microstructure (Electron Backscatter Diffraction -- EBSD) data at the integration points of finite elements. Very interestingly, the peaks (highest positions) and the valleys of a drawn cup could be predicted well by using a micro-macro approach via the crystal plasticity model. A good agreement between simulated results and experimental data provided by external research institutes of metal forming has been demonstrated. In general, this work allowed to target the demand for sheet metal parts in modern automotive industries such as the improvement of materials strength, low plasticity and difficult-to-form materials and complex-shaped parts.Outline of duties:1.
