变形高温合金标准中痕量元素控制要求浅析

Harmful trace element control in specification for superalloy wrought products

介绍了俄罗斯、英国、美国、法国以及我国航空发动机用变形高温合金材料标准中化学成分痕量元素的控制要求概况，分析了中外标准中变形高温合金痕量元素的控制要求特点，提出了开展中外高温合金有害痕量元素控制水平对比试验研究的建议，为评价高温合金材料纯净度水平以及高温合金研制中确定有害痕量元素的控制要求提供依据。

Trace element contents requirements of wrought superalloy for aero-engine in Russian, British, American, French and Chinese standards are introduced. The features of these requirements are analyzed and contrast test research of trace element contents control levels between Chinese and foreign standards is proposed, which will provide a basis to determine the trace element contents requirements and cleanliness of superalloy.
