Abstract Scope |
A novel idea to create new alloys for Additive manufacturing (AM) by mixing a small addition of nanoparticles with bulk material was put forward. Integrated Computational Material Engineering (ICME) may be used to guide the AM process, predict thermal behaviour, optimize process parameters, secure net-shape, and qualify parts. Modelling is needed to predict
the effect of defects and the effect of inclusions on mechanical properties, build quality and in-service performance.
ICME can reduce trial-and-error fabrication and establish an AM digital twin, thereby accelerating part qualification and AM adoption. AM creates complex thermal processes which impact material microstructure and result in changes to mechanical properties in terms of strength and plasticity. In this study, Grain-Boundary Engineering (GBE) and multi-scale modelling
are performed to expedite qualification of new and existing AM polycrystalline alloys. |
