摘要
摘要 在不同回火条件(温度和时间)下,研究了 Nb 对 10Cr-3Co-2W 马氏体耐热钢中奥氏体晶粒长大动力学的影响。结果表明,铌能有效细化奥氏体晶粒尺寸;这一结果归因于铌原子溶质拖曳效应和 NbC 沉淀的钉扎效应的共同作用。根据测量值,建立了一个经验模型来预测该合金体系的晶粒生长行为。此外,还得出了应用于 MatCalc 软件微结构演变模型的关键条件和参数。研究结果将有助于预测不同铌含量和温度参数下的晶粒大小,并为设计热处理工艺和合金提供有用信息。
Effect of Nb on Austenite Grain Growth in 10Cr-3Co-2W Martensitic Heat-Resistant Steel
Abstract
The effect of Nb on austenite grain growth kinetics was investigated in 10Cr-3Co-2W martensitic heat-resistant steel under various tempering conditions (temperature and time). The results demonstrate that Nb effectively refines the austenite grain size; this result is attributed to the combined effect of Nb atom solute drag effect and pinning effect of NbC precipitates. Based on the measured values, an empirical model was developed to predict the grain growth behavior of this alloy system. In addition, the key conditions and parameters for application to the microstructure evolution model of MatCalc software were derived. Results will enable the prediction of grain size at different Nb contents and temperature parameters, and provide useful information for designing heat treatment processes and alloys.
期刊介绍:
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
