摘要

摘要对2.25Cr1Mo0.3 V压力容器钢不同温度下用常规方法建立的断裂数据模型与用参数化数值等温基准(P-NID)方法建立的相同数据模型进行比较。备选模型是根据它们复制数据的准确性来评估的。讨论了从这些模型预测长期性质的信心，并认为主要的外推可能被认为是可靠的模型，满足P-NID程序的简单精度标准。关键词:蠕变破裂2.25 cr1mo0.3 v钢断裂建模长期外推p - nid程序准确性标准披露声明作者未报告潜在利益冲突。

Simplicity, accuracy and confidence in predicting long-term rupture properties from short-term data: a study of four heats of 2.25Cr1Mo0.3V steel

ABSTRACTModels of rupture data formulated recently by conventional methods for different heats of a 2.25Cr1Mo0.3 V pressure vessel steel are compared to models of the same data formulated by the P-NID (parametric, numerical isothermal datum) procedure. The alternative models are evaluated according to the accuracy with which they replicate the data. Confidence in the prediction of long-term properties from these models is discussed, and it is argued that major extrapolations may be considered reliable for models that satisfy the simple criteria of accuracy of the P-NID procedure.KEYWORDS: Creep rupture2.25Cr1Mo0.3V steelrupture modellinglong-term extrapolationP-NID procedurecriteria of accuracy Disclosure statementNo potential conflict of interest was reported by the author(s).

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.
