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

小行星9802804 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了支助。 本次会议是继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。 微结构演化是材料研究的前沿领域，晶粒生长是其中的核心课题。 有两个最近的事态发展，导致更强烈的研究兴趣，在这一领域。 一个是计算机模拟技术的进步，再加上不断增加的计算能力，能够提供现实的和统计上显着的预测微观结构的演变。 第二是发展能够精确描述微观结构（晶粒尺寸、形状、晶体取向等）的自动化实验技术。以提供微观结构良好统计描述。 这些实验技术中的主要技术是利用扫描电子显微镜的纹理测量能力的取向成像显微镜。 计算和实验的这些并行发展使这次会议及时，使理论建模者和实验研究者之间发生直接的互动。 这一专题会议汇集了世界领先的谷物生长科学家。 这项支持有助于支付来自国外的杰出演讲者的旅费，并为学生合著者提供旅费赠款。 在冶金学和陶瓷学中，众所周知，微观结构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变的核心。 晶粒生长的结果在决定金属、陶瓷和其它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，金属和材料协会组织，ASM国际和材料研究协会共同赞助，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. ***
