Computational modelling of dynamic recrystallisation of Ni-based superalloy during linear friction welding
Okeke, Saviour I.; Harrison, Noel M.; Tong, Mingming (Springer, 2022-01-12)Linear friction welding (LFW) is an advanced joining technology used for manufacturing and repairing complex assemblies like blade integrated disks (blisks) of aeroengines. This paper presents an integrated multiphysics ... -
Dissolution of delta phase in Ni-based superalloy during linear friction welding: integrated multiphysics computational process modelling
Okeke, Saviour I.; Harrison, Noel M.; Tong, Mingming (Springer, 2021-06-15)Linear friction welding (LFW) is an increasingly popular solid-state joining method for challenging applications such as integrated blade disk of aero-engines. However, the influence of friction-generated heat on the ... -
Efficiency and accuracy of GPU-parallelized Fourier spectral methods for solving phase-field models
Boccardo, Adrian; Tong, Mingming; Leen, Sean B.; Tourret, Damien; Segurado, Javier (Elsevier, 2023-06-15)Phase-field models are widely employed to simulate microstructure evolution during processes such as solidification or heat treatment. The resulting partial differential equations, often strongly coupled together, may be ... -
Prediction of microstructure evolution for additive manufacturing of Ti-6Al-4V
Yang, Xinyu; Barrett, Richard A.; Tong, Mingming; Harrison, Noel M.; Leen, Sean B. (Elsevier, 2020-04-26)A key challenge for successful exploitation of additive manufacturing (AM) across a broad range of industries is the development of fundamental understanding of the relationships between process control and mechanical ... -
Thermomechanical modelling for the linear friction welding process of Ni-based superalloy and verification
Okeke, Saviour I.; Harrison, Noel M.; Tong, Mingming (SAGE Publications, 2020-01-22)This paper presents a fully coupled thermomechanical model for the linear friction welding process of Inconel-718 nickel-based superalloy by using the finite element method. Friction heat, plastic work, and contact formulation ... -
Towards a process-structure model for Ti-6Al-4V during additive manufacturing
Yang, Xinyu; Barrett, Richard A.; Tong, Mingming; Harrison, Noel M.; Leen, Sean B. (Elsevier, 2020-12-15)This paper presents the development of an integrated approach for microstructure prediction in laser beam powder bed fusion (PBF-LB) manufacturing of Ti-6Al-4V, primarily focused on the solidification morphology and ...
