Nontechnical AbstractMetallic glasses were discovered over one-half of a century ago. It was immediately clear that these are fascinating novel materials. They have led to new insights into the reasons for glass formation and the processes by which a liquid turns into a glass upon cooling. Additionally, sustained research has shown that they have superior properties that make them of potential technological interest. These include strengths greater than those of steels, high hardness and good corrosion resistance. However, the first glasses required that the liquid be cooled at rates approaching one million degrees per second, limiting their practical applications. About 20 years ago new families of metallic glasses (?Bulk Metallic Glasses,? or BMGs) were discovered, which could be formed and processed in ways similar to those used for more common glasses. This caused an intense resurgence of research that now appears to be moving metallic glasses from the laboratory into the market place. To sustain this fast paced fundamental and technological research, frequent conferences and workshops are needed for scientists and engineers to present new results and exchange ideas. Because of the intense activity of this field in Asia, almost all of the meetings of the BMG conference series, the central conference for bulk metallic glasses, have taken place there. The only one held outside of Asia was BMG IV, held in 2005 in the United States. Travel expenses and limited research funds has limited the participation of US scientists, post-docs and students in these conferences. The support provided for BMG XI, which is to be held from June 5 ? 9, 2016 on the campus of Washington University in St. Louis, Missouri, will enable broader participation of US students and young researchers.  Technical AbstractMetallic glasses, first discovered in 1960, remained primarily a laboratory curiosity for most of the time between 1960 and 1990. The extremely high cooling rates required for the liquid to form a glass (105 oC to 106 oC) limited their usefulness. In spite of this, a few applications did emerge during this time. Their combination of high electrical resistivity, low susceptibility and low magnetic coercivity, for example, led to their use as core materials for high-quality electrical transformers. In the 1990s, new families of metallic glasses (?Bulk Metallic Glasses,? or BMGs) were discovered that formed at much lower cooling rates and could be processed under conditions similar to those used for silicate glasses. This led to an intense research activity, now resulting in the emergence of metallic glasses as potentially very important new technological materials. Because the research activity is particularly intense in Asia, almost all of the meetings in the BMG conference series (the central conference for bulk metallic glasses) have taken place there. The last BMG meeting outside of Asia was held in the US in 2005 (BMG IV). The increasingly limited research funding and significant travel expenses have resulted in small US participation in these conferences, particularly among young US researchers and students. To maintain a vibrant research activity, it is critical that researchers meet frequently to exchange ideas and present new results. The lack of significant US participation in this series, particularly among our future scientific leadership, hampers US advancements in this important field. To address this, BMG XI will be held from June 5 ? 9, 2016 on the campus of Washington University in St. Louis, Missouri. Many outstanding issues of basic and practical importance will be discussed, including glass design, stability and relaxation, structure, dynamics, properties, and applications. For the first time, panels will discuss establishing testing standards and explore new manufacturing possibilities that take full advantage of the unique properties of metallic glasses. Two keynote, 10 plenary, 22 invited and 58 contributed oral presentations are scheduled, along with 28 poster presentations. To encourage greater participation among US graduate student and young faculty, funds will be used to provide travel and/or registration assistance. By hosting BMG XI in the US, we are increasing the US participation, which will allow US researchers to be exposed to cutting edge ideas and results, and provide new opportunities for interaction and collaborations.

金属玻璃是在半个多世纪前发现的。 很明显，这些都是令人着迷的新材料。 它们使人们对玻璃形成的原因以及液体在冷却时变成玻璃的过程有了新的认识。 此外，持续的研究表明，它们具有上级特性，使它们具有潜在的技术价值。 这些包括强度大于钢，高硬度和良好的耐腐蚀性。 然而，第一批玻璃需要液体以接近每秒一百万度的速度冷却，这限制了它们的实际应用。 大约20年前，新的金属玻璃家族（？散装金属玻璃，？或BMG），其可以以与用于更普通的玻璃的方式类似的方式形成和处理。这引起了研究的激烈复苏，现在似乎正在将金属玻璃从实验室推向市场。 为了维持这种快节奏的基础和技术研究，科学家和工程师需要频繁的会议和研讨会来展示新的成果和交流想法。 由于这一领域在亚洲的激烈活动，几乎所有的BMG会议系列会议，即大块金属玻璃的中心会议，都在那里举行。 唯一一次在亚洲以外举行的是2005年在美国举行的BMG IV。 旅行费用和有限的研究资金限制了美国科学家，博士后和学生参加这些会议。 为将于6月5日举行的BMG XI提供的支持？2016年9月9日在密苏里州圣路易斯的华盛顿大学校园举行，将使美国学生和年轻研究人员能够更广泛地参与。  技术摘要金属玻璃于1960年首次发现，在1960年至1990年间的大部分时间里，它仍然主要是实验室的好奇心。 液体形成玻璃所需的极高冷却速率（105 ℃至106 ℃）限制了它们的用途。 尽管如此，在这段时间里还是出现了一些应用程序。 例如，它们的高电阻率、低磁化率和低磁导率的组合导致它们被用作高质量电力变压器的芯材料。 在20世纪90年代，新的金属玻璃家族（？散装金属玻璃，？或BMG），其在低得多的冷却速率下形成，并且可以在类似于用于硅酸盐玻璃的条件下加工。 这导致了激烈的研究活动，现在导致金属玻璃作为潜在的非常重要的新技术材料的出现。 由于研究活动在亚洲特别活跃，BMG会议系列（大块金属玻璃的中心会议）的几乎所有会议都在那里举行。 亚洲以外的最后一次BMG会议于2005年在美国举行（BMG IV）。 越来越有限的研究经费和大量的差旅费导致美国参加这些会议的人数很少，特别是美国年轻的研究人员和学生。 为了保持一个充满活力的研究活动，这是至关重要的，研究人员经常见面，交流思想和提出新的成果。 美国在这一系列中缺乏重要的参与，特别是在我们未来的科学领导中，阻碍了美国在这一重要领域的进步。 为了解决这个问题，BMG XI将于6月5日举行？2016年9月9日，在密苏里州圣路易斯的华盛顿大学校园内。 将讨论许多具有基本和实际重要性的突出问题，包括玻璃设计、稳定性和弛豫、结构、动力学、性能和应用。 专家小组将首次讨论建立测试标准，并探索充分利用金属玻璃独特性能的新制造可能性。 计划举行两次主旨发言、10次全体会议、22次应邀发言和58次自愿发言，沿着还有28次海报发言。 为了鼓励美国研究生和年轻教师更多地参与，资金将用于提供旅行和/或注册援助。 通过在美国举办BMG XI，我们正在增加美国的参与，这将使美国研究人员能够接触到最前沿的想法和结果，并为互动和合作提供新的机会。
