Development of the evaluation of the crack depth by the magnetic inspection method

Study period:2000 - 2000
Organization (1):
Investigating Researcher (3):
Research overview:
Measurement of a crack is indispensable in order to perform life evaluation of apparatus and a structure. A fatigue crack is created to the carbon-steel materials for machine structure, low alloys steel materials, and spherical cast iron. Magnetic flux leakage produced from these peaces is recorded to magnetic tape or magnetic sheet.
