摘要： PROBLEM TO BE SOLVED: To provide a detection method of solidification structure for a steel type of which the concentration difference caused by segregation of a solute element being solidified is comparatively small, in particular, for low-carbon steel of which the carbon concentration is lower than or equal to 0.01 mass%.SOLUTION: A sample cross section of a steel cast piece is polished. Thereafter ultrasonic waves of two or more kinds of frequencies different from each other are alternately and intermittently applied, within a range of 30 kHz to 3 MHz, to a corrosion liquid 15 using water containing micro bubbles as a solvent. While water-resonating the corrosion liquid 15, the sample cross section is corroded and a solidification structure of steel appears. Thereafter, the steel cast piece is washed and dried, a corrosion pit formed on the sample cross section is filled with polishing powder, and a transparent adhesive tape is stuck to the sample cross section. After the polishing powder in the corrosion pit is adhered to the transparent adhesive tape, the transparent adhesive tape is released and next, the transparent adhesive tape is stuck on a white pasteboard.
