| titleOfInvention | High-silicon high-carbon steel wire rod austenite grain size measuring method |
| abstract | The application discloses a method for measuring austenite grain size of a high-silicon high-carbon steel wire rod, which comprises the following steps: s1 sample preparation, namely processing the wire rod into a round rod with the length of 10cm and the diameter of 6 mm; s2 sample processing, namely heating the round bar on a thermal simulation testing machine to 850-1200 ℃, preserving heat for 10-60min, then cooling to 700-720 ℃ at the speed of 30K/S, preserving heat for 10min, and finally rapidly cooling to room temperature; and (8) observing an S3 sample, namely cutting, inlaying and polishing the sample treated by the S2 sample, then corroding the sample with a sodium picrate aqueous solution, and then measuring the size of crystal grains by using a metallographic microscope. The method has the advantages that the prior austenite grains can be clearly displayed, the image on the whole section of the sample is very clear, the success rate is high, and the requirements of scientific research can be met. |
