Gordon Research Conference on Physical Metallurgy "Time Dependent Behavior in Metals", June 26 - July 2, 1994, at the Holderness School in Plymouth, NH

9412394为1994年戈登物理冶金研究会议“金属的时间依赖性行为：长期测量和建模”提供了风暴支持。本次会议的目的是提供一个论坛，积极讨论国家的最先进的实验和建模技术，旨在了解复杂的损伤现象，在金属演变的长时间。这种损伤通常涉及微观结构变化、表面化学或电化学反应性、塑性变形、溶质偏析、微损伤演化和导致裂纹形成和扩展的氢相互作用的耦合。演讲者和讨论围绕关键主题组织，包括施加应力和应变下的微观组织演变，高温下裂纹的形成和扩展，环境与裂纹的相互作用，溶质元素对变形和断裂的影响，环境诱导的裂纹，以及应力下的局部腐蚀。该计划的一个重点是整合物理和机械冶金的观点，这在前几年已经分开。迫切需要从跨学科和科学的角度来考虑这些问题，因为国家基础设施正在老化，人们正在考虑和设计使用先进材料的长寿命系统。虽然从科学的角度来看，这些问题很复杂，但大学、工业和国家实验室的研究人员正在用令人兴奋的高分辨率实验工具、理论和模拟建模来解决这些问题。＊＊＊

9412394 Storm Support is provided for the 1994 Gordon Research Conference on Physical Metallurgy "Time-Dependent Behavior in Metals: Measurement and Modeling for the Long Term". The goal of this conference is provide a forum for active discussions on state-of- the-art experimental and modeling techniques aimed at understanding complex damage phenomena that evolve in metals over long times. Such damage often involves the coupling of microstructural changes, surface chemical or electrochemical reactivity, plastic deformation, solute segregation, microdamage evolution and hydrogen interactions leading to crack formation and growth. The speakers and discussion have been organized around critical topics, including microstructural evolution under applied stress and strain, crack formation and growth at elevated temperatures, the interaction of environment with such cracking, the effect of solute elements on deformation and fracture, environmentally-induced cracking, as well as localized corrosion under stress. A focus of this program is the integration of physical and mechanical metallurgy perspectives which have been separated in previous years. %%% There is a pressing need to consider these problems from an interdisciplinary and scientific perspective because the national infrastructure is aging and long-life systems are being contemplated and designed with advanced materials. Although such problems are complex from a scientific viewpoint, researchers in universities, industry and national laboratories are now addressing them with exciting high resolution experimental tools, theory and simulation modelling. ***
