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. ***

小行星9412394 为1994年戈登物理冶金研究会议“金属的时间依赖行为： 长期的测量和建模”。 本次会议的目标是提供一个论坛，积极讨论最先进的实验和建模技术，旨在了解金属中长期演变的复杂损伤现象。 这种损伤往往涉及耦合的微观结构的变化，表面化学或电化学反应，塑性变形，溶质偏析，微观损伤演变和氢的相互作用，导致裂纹的形成和增长。 演讲者和讨论围绕关键主题进行，包括施加应力和应变下的微观结构演变，高温下裂纹的形成和生长，环境与此类裂纹的相互作用，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。 该计划的重点是物理和机械冶金观点的整合，这些观点在前几年已经分开。 从跨学科和科学的角度考虑这些问题是迫切需要的，因为国家基础设施正在老化，并且正在考虑使用先进材料设计长寿命系统。 虽然从科学的角度来看，这些问题是复杂的，但大学，工业和国家实验室的研究人员现在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。 ***
