As one of the important aspects of superalloy cleanliness, the quantity and size of inclusions significantly affect the quality of superalloy products. Combined with many years’ experience in scientific research and production, the merits and demerits of several quantitative/qualitative evaluation methods in evaluating the cleanliness of superalloy were discussed, such as metallographic image analysis, slag test, electrolytic extraction, etc. Electron beam button method is introduced and compared with the traditional evaluation technology.
