| Popis: | International audience; Liquid metal embrittlement of an otherwise ductile material is an en vironmentally induced fracture phenomenon characterized by poten tially high brittle crack propagation rate and deleterious effects onmechanical properties. Its phenomenology is still not well understood,in particular in terms of prediction of sensible couples and about thedetailed intergranular fracture mechanisms. Here we will report onthe study in the copper systems via both an energetic and QM/MMapproaches at the atomic level to predict the sensitivity of model ma terials to liquid metal embrittlement. The main goal is to try to linkmicro-testing (flexion in FIB prepared samples or by in-situ TEM) toa sound modelling at the atomistic scale via fracture mechanics typesollicitations. The progress towards predictability of liquid metal em brittlement systems and understanding of fracture mechanisms will bepresented along with a vision about their experimental validation. |
