Title:
水素誘起割れ測定方法および測定装置
Document Type and Number:
Japanese Patent JP6394933
Kind Code:
B2
Abstract:
There are proposed a method for measuring hydrogen-induced cracking which can measure hydrogen-induced cracking initiated in an interior of a test specimen during HIC test and a measuring apparatus used in this method. When cracks initiated in an interior of a test specimen 1 immersed in a test solution 5 containing hydrogen sulfide is measured by an ultrasonic probe 2 placed in a vessel 3, the position and size of cracks initiated in the interior of the test specimen 1 are measured with the lapse of time at a state of immersing the test specimen 1 in the test solution by scanning the ultrasonic probe 2 or the test specimen 1.
