摘要

锅炉管的失效分析和寿命预测需要了解管段的实际使用温度状况。显微组织的粗化（老化）直接与使用时间和温度相关，因而可通过研究碳化物粗化动力学及测定碳化物尺寸来评定管段平均使用温度。本文介绍了12Cr1MoV钢碳化物粗化动力学模型，并提出评定寿命的“极限尺寸”模型。

Abstract

Failure analysis and life assessment of boiler tubes require precise knowledge of the real operating time. Coarseness of the microstructure is take-and temperature - dependent. Thus

a "mean" operating temperature may be estimated with study of the coarsening kinetics and measurement of carbide size. In this paper a carbide coarsening kinetics model of 12Cr1MoV steel is described and a model of the "critical size" analysis for life estimation is proposed.
