摘要

PPROBLEM TO BE SOLVED: To provide a method for measuring prior austenite () grain boundaries of steel having a high-purity prior austenite grain boundary structure. PSOLUTION: The steel having the prior austenite grain boundary structure is immersed in a picric acid saturated aqueous solution, and then immersed in a thiosulfuric acid sodium saturated aqueous solution to selectively corrode the prior austenite () grain boundaries.
