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

1998年6月14日至19日在宾夕法尼亚州匹兹堡的卡内基梅隆大学举行的第三届国际谷物生长会议提供了支持。这次会议是继在意大利罗马（1991年）和日本北九州（1995年）举行的前两次会议之后举行的。显微组织演化是近年来材料研究的前沿领域，晶粒生长是其中的核心课题。最近有两项进展引起了人们对这一领域更强烈的研究兴趣。一个是计算机模拟技术的进步，加上不断增长的计算能力，能够给出微观结构演变的现实和统计上有意义的预测。二是发展自动化实验技术，能够足够详细地准确描述微观结构（晶粒尺寸、形状、晶体取向等），从而提供良好的微观结构统计描述。在这些实验技术中，主要是利用纹理测量能力的定向成像显微镜扫描电子显微镜。计算和实验的并行发展使这次会议及时召开，以便理论建模者和实验研究者之间进行直接的互动。这次专题会议汇集了世界粮食生长领域的顶尖科学家。这项资助帮助支付来自国外的杰出演讲者的旅行费用，并为学生合著者提供旅行补助金。众所周知，在冶金和陶瓷领域，微观结构的控制是基于加工条件和成分的选择，这为改善材料性能提供了一条途径。在广泛的条件下，晶粒生长是微观结构演化的核心。晶粒生长的结果在决定金属、陶瓷和其他细晶粒材料的可制造性和使用寿命方面具有相当大的技术和工业重要性。匹兹堡会议由矿物、金属和材料学会组织，ASM国际和材料研究学会共同赞助，涉及材料中晶粒生长的各个方面。＊＊＊

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. ***
