Overall Eurocores Activity Summary This EuroMinScI activity will bring together a network of 10 mineral and material science partners from academia and national research institutes with the aim to significantly improve our knowledge of dynamics of substructure formation and evolution in rocks and metals. The consortium is designed to break the traditional barriers that exist between the methodologies of experiments and modelling. It will integrate the currently fragmented research efforts undertaken in various EU-states, with the aim of fostering a viable network with a lifetime well beyond that of this activity. Six Early Stage Researchers and three Experienced Researchers will jointly address the dynamics of substructures within grains in polycrystalline materials. This CPR is pioneering in its integration of in situ experimental techniques with multi-scale numerical simulations, both research areas currently at the forefront of modern research. This combination is particularly powerful as in situ techniques provide the only experiments capable of providing coherent observations in the form of a time series. These time series are crucial for the validation and extension of numerical simulations, as the post-mortem examinations which are available from traditional experimental approaches provide significantly more limited constraints for modelling. This CPR will deliver new insights in questions including How do new (sub-) grains nucleate and evolve? What are the properties and behaviour of subgrain boundaries? How do processes at different scales interact, from dislocations to whole grains? In addition, significant progress in the modelling of substructure processes will be made by linking and developing hybrid models and interfacing different numerical approaches. Through a system of joint short courses, multilateral supervision and exchanges between the hosts, the young researchers will be exposed to different schools of thought and will have the unique opportunity to gain expertise in a wide range of experimental and numerical techniques and their combination.

Eurocores 总体活动摘要 这项 EuroMinScI 活动将汇集来自学术界和国家研究机构的 10 个矿物和材料科学合作伙伴网络，旨在显着提高我们对岩石和金属的亚结构形成和演化动力学的了解。该联盟旨在打破实验和建模方法之间存在的传统障碍。它将整合目前在各个欧盟国家进行的分散的研究工作，目的是培育一个可行的网络，其寿命远远超出该活动的寿命。六名早期研究人员和三名经验丰富的研究人员将共同研究多晶材料晶粒内亚结构的动力学。该 CPR 在将原位实验技术与多尺度数值模拟相结合方面处于领先地位，这两个研究领域目前都处于现代研究的前沿。这种组合特别强大，因为原位技术提供了唯一能够以时间序列形式提供相干观测的实验。这些时间序列对于数值模拟的验证和扩展至关重要，因为传统实验方法中的事后检查为建模提供了更加有限的约束。该 CPR 将为问题提供新的见解，包括新（子）颗粒如何成核和演化？亚晶界的性质和行为是什么？从位错到全谷物，不同尺度的过程如何相互作用？此外，通过链接和开发混合模型以及连接不同的数值方法，将在子结构过程建模方面取得重大进展。通过联合短期课程、多边监督和主办方之间的交流体系，年轻的研究人员将接触到不同的思想流派，并将有独特的机会获得广泛的实验和数值技术及其组合的专业知识。
