MINSUBSTRDYN. Subgrain structure development in rocks and metals

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中子结构形成和演化动力学的了解。该联盟旨在打破实验方法和建模方法之间存在的传统障碍。它将整合目前在欧盟各国开展的分散的研究工作，目的是建立一个可行的网络，其寿命远远超过这项活动。六名早期研究人员和三名经验丰富的研究人员将共同解决多晶材料中晶粒内部子结构的动力学问题。这CPR是开创性的集成原位实验技术与多尺度数值模拟，这两个研究领域目前处于现代研究的前沿。这种结合特别强大，因为现场技术提供了唯一能够以时间序列的形式提供连贯观测的实验。这些时间序列是至关重要的验证和扩展的数值模拟，作为事后检查，这是从传统的实验方法提供了显着更有限的约束建模。这个CPR将提供新的见解的问题，包括如何新的（亚）颗粒成核和演变？亚晶界的性质和行为是什么？从位错到全晶粒，不同尺度的过程如何相互作用？此外，将通过连接和开发混合模型以及连接不同的数值方法，在子结构过程建模方面取得重大进展。通过联合短期课程，多边监督和东道主之间的交流系统，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。

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.
