NON-TECHNICAL SUMMARY:The 2015 Gordon Research Conference (GRC) on Physical Metallurgy reviews the current state of knowledge with respect to key aspects of the discipline. The presenters, discussion leaders, poster presenters and other participants debate the state of the art and which problems are most deserving of the researchers in the field. The GRC format emphasizes equal parts presentation and discussion, with only 22 talks altogether and active leadership of the discussion, which maximizes the opportunities for young researchers to learn about new ideas and problems. The presenters and discussion leaders have been selected based on their leadership in their respective areas and for their capacity for thought-provoking lectures. We anticipate that the conference attendance is close to the maximum of 200, of which approximately 40 % are expected to be students and postdocs. Therefore the educational impact on young researchers is substantial. We expect about 10 % to be assistant professors i.e. academics at an early career stage. The technical topics include 3D printing of metals, image analysis and data science. The 3D printing of metals is a prime example of a new and potentially disruptive technology that also has the potential to open up new lines of research in physical metallurgy because of its novel processing characteristics. Therefore the technical impact of the meeting is likely to be high because of the unusual mix of topics.TECHNICAL SUMMARY:The 2015 Gordon Research Conference on Physical Metallurgy examines the future of the discipline. Revolutionary new high-resolution experimental tools are emerging that permit multi-modal characterization in all three spatial dimensions as well as time. At the same time, theory is maturing and modeling/simulation methods to test it are advancing at a tremendous pace. These are tools that allow us to address a key issue, which is 'How to exploit materials for best effect'? Accordingly, the topics that are addressed in order to understand where the current frontiers in Physical Metallurgy lie include: nucleation of precipitation, dislocations, damage; deterministic versus statistical modeling, e.g. fatigue cracking; microstructural design on the 5-1000 nm size scale; studies and modeling of ductility - as a proxy for failure; science behind modern processing techniques (rapid prototyping, interface bonding, plasma sintering); designing metastable structures, e.g. metallic glasses, nanostructures, layered composites and coatings; advanced microscopy and image analysis; and additive manufacturing (3D printing). As is the tradition of the Gordon Research Conferences, the meeting is founded on several fundamental pillars, namely to explore the frontiers of the discipline, to foster debate on the future of Physical Metallurgy, to present unpublished and speculative work, and to engage world-class speakers. Junior researchers i.e. postdocs and students are encouraged to attend because a large fraction of the available time is devoted to discussion and debate. To emphasize this point, the time devoted to talks is roughly equal to the time for discussion and presenters are strongly encouraged to discuss current, unpublished work, based on strict rules that bar citation or quotation from the meeting. In summary, this meeting offers a unique opportunity to learn about new developments and trends in Physical Metallurgy.

非技术摘要：关于物理冶金学的2015年戈登研究会议（GRC），就该学科的关键方面而言，当前的知识状态。 主持人，讨论的领导者，海报演示者和其他参与者辩论艺术的状态，哪些问题最值得该领域的研究人员。 GRC格式强调了平等的演讲和讨论，只有22个谈判和讨论的积极领导才能，这使年轻研究人员了解新的思想和问题的机会最大化。 主持人和讨论领导者是根据他们在各自领域的领导以及他们发人深省讲座的能力的选择。 我们预计会议的出席率接近最多200，其中约40％是学生和博士后。 因此，对年轻研究人员的教育影响是巨大的。 我们预计在早期职业阶段，约有10％是助理教授，即学者。 技术主题包括金属的3D打印，图像分析和数据科学。 金属的3D打印是一种新的且潜在的破坏性技术的一个典型例子，该技术也有可能因其新颖的加工特性而开放物理冶金研究的新研究。 因此，由于主题的异常组合，会议的技术影响可能很高。技术摘要：2015年戈登冶金研究会议研究了该学科的未来。 革命性的新高分辨率实验工具正在出现，可以在所有三个空间维度和时间上进行多模式表征。 同时，理论正在成熟和建模/仿真方法，以测试它的进步。 这些工具使我们能够解决一个关键问题，这是“如何利用材料以获得最佳效果”？ 因此，为了了解当前物理冶金中的当前边界包括：降水的成核，脱位，损坏的成核；确定性与统计建模，例如疲劳破裂； 5-1000 nm尺寸尺度上的微观结构设计；延展性的研究和建模 - 作为失败的代理；现代加工技术的科学（快速原型，界面键合，等离子体烧结）；设计亚稳态，例如金属眼镜，纳米结构，分层复合材料和涂料；高级显微镜和图像分析；和增材制造（3D打印）。与戈登研究会议的传统一样，会议建立在几个基本支柱上，即探索学科的边界，以促进有关物理冶金的未来的辩论，以展示未出版和投机性的工作，并参与世界 - 参与世界 - 参与世界 - 班级演讲者。 初级研究人员即鼓励博士后和学生参加，因为可用时间的很大一部分专门用于讨论和辩论。 要强调这一点，专门讨论会谈的时间大致等于讨论的时间，强烈鼓励主持人根据严格的规则来讨论当前未发表的作品，这些规则是在会议上引用或报价的严格规则。 总而言之，这次会议提供了一个独特的机会，可以了解物理冶金的新发展和趋势。
