摘要

日本于1999年制定了《老旧火电设备剩余寿命评估国家指南》。随着老化系统的增加，近年来出现了一些问题，包括意外蠕变损伤模式的出现，实验室生成的损伤校准曲线的实用性验证，如何处理由于工厂启动和停止次数增加而引起的蠕变疲劳损伤，加速蠕变试验中塑性变形的发生以及工厂运行过程中蠕变损伤监测方法的必要性。日本材料科学学会于2011年成立了推进剩余寿命评估技术工作组，以确定问题并讨论改进措施。本文概述了工作组活动的结果。

Activities to advance residual life evaluation techniques for highly aged power boiler materials

ABSTRACT In Japan, national guidelines of residual life evaluation for aged thermal power equipment were formulated in 1999. Several issues had recently come to light with the increase in ageing systems, including the emergence of unexpected mode of creep damage, the verification of practical applicability of the damage calibration curve generated in the laboratory, how to deal with creep-fatigue damage due to increased numbers of plant starts and stops, occurrence of plastic deformation in the accelerated creep test and the need for the creep damage monitoring method during plant operation. The Working Group to Advance Residual Life Evaluation Techniques was established in 2011 within the Society of Materials Science, Japan, to identify issues and discuss improvement measures. This paper provides an overview of the results of the working group activities.

期刊介绍： Materials at High Temperatures welcomes contributions relating to high temperature applications in the energy generation, aerospace, chemical and process industries. The effects of high temperatures and extreme environments on the corrosion and oxidation, fatigue, creep, strength and wear of metallic alloys, ceramics, intermetallics, and refractory and composite materials relative to these industries are covered. Papers on the modelling of behaviour and life prediction are also welcome, provided these are validated by experimental data and explicitly linked to actual or potential applications. Contributions addressing the needs of designers and engineers (e.g. standards and codes of practice) relative to the areas of interest of this journal also fall within the scope. The term ''high temperatures'' refers to the subsequent temperatures of application and not, for example, to those of processing itself. Materials at High Temperatures publishes regular thematic issues on topics of current interest. Proposals for issues are welcomed; please contact one of the Editors with details.
