1.绪言 在耐热钢主题中,为开发用于650℃、300大气压下的超临界压火力发电设备的锅炉用系列大口径厚壁钢管的主蒸气管及集管的高Cr铁素体系列耐热钢进行了基础研究。本文就耐热钢的研究总体至目前为止所取得的进展以及材料研究——形成结构体——评价的各螺旋之间的联系和今后研究的方向进行了讨论。
1. INTRODUCTION In the subject of heat-resisting steels, a series of high-Cr ferrites for the development of main steam pipes and headers for large-diameter, thick-walled steel pipes for boilers used in supercritical pressure thermal power generation equipment at 650 ° C and 300 atmospheres Heat-resistant steel for basic research. This article discusses the progress made so far in the study of heat-resisting steels and the relationship between the various spirals in the material research-formation structure-evaluation and the future research directions.
