The Mechanisms of the Massive Transformation; St. Louis, MO; October 8-12, 2000

9987125艾伦这个项目是对将于2000年秋季在密苏里州圣路易斯举行的TMS/ASM会议(10月8日至12日)期间举行的“大规模变革的机制”研讨会的部分支持。由ASM相变委员会赞助。在这次研讨会上要考虑的主要问题是T零点温度或Solvus温度作为块状相变的温度上限，以及块状/基质边界的结构是否是非相干的或部分相干的。许多金属合金系统以及氧化铝和铋氧化物基陶瓷中的大量合金系统中的大量相变的实验和理论研究将被报道。此外，大规模生长动力学分析中的一个中心方面，即相间边界的扩散率，将是一套四篇论文的主题。其中三个将是实验性的，与测量相界上的扩散系数有关。第四种方法将基于计算机模拟，试图将跨相界面的扩散系数(尚不能独立确定，而是目前根据生长动力学数据进行评估)与沿相同边界的扩散系数进行比较。在专题讨论会的最后一届会议期间，将举行一般性讨论。财政支持包括：(I)特别重要的参与者，荣誉退休教授Mats Hillert(皇家学院)的航空旅行和住宿。(Ii)与一般性讨论有关的费用，以及(Iii)为五名研究生出席研讨会提供部分支助。%几种金属合金会发生大量相变，影响合金的组织和性能。研讨会将突出这一转变的特点，并试图解决几个悬而未决的问题。会议将由讨论者和专题讨论会组织者(V.K.瓦苏德万和H.I.Aaronson)录制、转录和编辑。在编辑D.E.Laughlin教授的监督下通过杂志的同行评审系统后，已获得冶金和材料交易A的许可，可以在本杂志上发表研讨会论文和一般讨论论文。*

9987125AaronsonThis project is the partial support of a symposium on "The Mechanisms of the Massive Transformation", to be held during the Fall, 2000 TMS/ASM Meeting (Oct. 8 - 12) in St. Louis, MO. under the sponsorship of the ASM Phase Transformations Committee. The principal issues to be considered during this symposium are whether the T zero temperature or the solvus temperature serves as the upper temperature limit of the massive transformation and whether the structure of massive/matrix boundaries is incoherent or partially coherent. Experimental and theoretical studies on the massive transformation in a wide range of alloy systems will be reported in both numerous metallic alloy systems as well as alumina and in bismuth oxide-based ceramics. Additionally, a central aspect in the analysis of massive growth kinetics, namely, the diffusivity in interphase boundaries, will be the subject of a set of four papers. Three of which will be experimental and concerned with measurement of the diffusivities along interphase boundaries. The fourth will be based upon computer simulations, in which attempts will be made to compare diffusivities across interphase boundaries (which cannot yet be determined independently and is instead presently evaluated from growth kinetics data) with diffusivities along the same boundaries. During the last session of the symposium, a General Discussion will be held. Financial support covers: (i) the airline travel and accommodations of a particularly important participant, Prof. Emeritus Mats Hillert (Royal Inst. of Technology, Stockholm), (ii) the expenses to be incurred in connection with the General Discussions session and (iii) partial support for attendance at the symposium by five graduate students. %%%Several metal alloys can undergo massive phase transformations, which affect the structure and properties of the alloy. The symposium will highlight features of this transformation and attempt to resolve several outstanding issues. The session will be recorded, transcribed and edited by both the discussers and the symposium organizers (V. K. Vasudevan and H. I. Aaronson). Permission has been secured from Metallurgical and Materials Transactions A to publish the symposium papers and the General Discussion paper in this journal, following passage through the journal's peer review system under the supervision of the Editor, Prof. D. E. Laughlin.***
