Third International Conference on Grain Growth, June 14-19, 1998, Pittsburgh, PA

9802804斯科特为1998年6月14日至19日在宾夕法尼亚州匹兹堡卡内基梅隆大学举行的第三届国际谷物生长会议提供支持。这次会议是继1991年在意大利罗马和1995年在日本北九州举行的会议之后举行的。微结构演化是近年来材料研究的前沿领域，而晶粒长大是一个核心课题。有两个最新的发展导致了对这一领域更强烈的研究兴趣。其一是计算机模拟技术的进步，再加上不断增长的计算能力，能够对微观结构的演变做出现实的、具有统计意义的预测。第二是开发能够准确描述微观结构(晶粒度、形状、晶体取向等)的自动化实验技术。足够详细，以提供对微观结构的良好统计描述。在这些实验技术中，主要的是利用扫描电子显微镜的纹理测量能力的定向成像显微镜。计算和实验方面的这些并行发展使这次会议变得及时，从而使理论建模人员和实验研究人员之间发生了直接的互动。这次专题会议汇聚了世界领先的谷物生长科学家。这项支持帮助支付了来自国外的杰出演讲者的旅费，并为学生合著者提供了旅费补助。%在冶金和陶瓷领域，众所周知，显微组织的控制是基于工艺条件和成分的选择，这为改善材料性能提供了一条途径。在广泛的条件下，颗粒生长是微观结构演变的核心。颗粒长大的后果在决定金属、陶瓷和其他细晶材料的可制造性和使用寿命方面具有相当重要的技术和工业意义。匹兹堡会议由矿物、金属和材料协会组织，ASM国际和材料研究学会联合赞助，讨论材料中颗粒生长的方方面面。***

9802804 Scott Support is provided for the Third International Conference on Grain Growth at Carnegie Mellon University, Pittsburgh, Pennsylvania, June 14-19, 1998. This conference follows previous conferences held in Rome, Italy (1991), and in Kitakyushu, Japan (1995. The field of microstructural evolution has recently come into the forefront of materials research and grain growth is a core topic. There are two recent developments which lead to more intense research interest in this field. One is the advance of computer simulation techniques which, coupled with ever increasing computational power, is capable of giving realistic and statistically significant predictions of microstructural evolution. The second is development of automated experimental techniques capable of accurately describing the microstructure (grain size, shape, crystallographic orientation, etc.) in sufficient detail as to provide good statistical descriptions of microstructure. Primary among these experimental techniques is orientational imaging microscopy using the texture measuring capability scanning electron microscopy. These parallel developments in computation and experiment make this conference timely so that direct interactions occur between the theoretical modelers and the experimental investigators. This special topics meeting brings together the world's leading scientists in grain growth. The support helps defray travel expenses for the distinguished speakers from abroad and provides travel grants for student co-authors. %%% It is well known in both metallurgy and ceramics that microstructure control is based on processing conditions and choice of composition, and this provides a pathway to improved material properties. Under a broad range of conditions grain growth lies at the heart of microstructural evolution. The consequences of grain growth are of considerable technological and industrial importance in determining the manufacturability and service life of met als, ceramics, and other fine grain materials. The Pittsburgh conference organized by The Mineral, Metals and Materials Society with co-sponsorship by ASM International and Materials Research Society deals with all aspects of grain growth in materials. ***
