... diffraction analysis showed that the carbides were primarily chromium based (Cr 23 C 7 and Cr 7 C 3 ). The sooty substance was identified as graphite. Wasted areas were ferromagnetic and the degree of ferromagnetism was directly related to the degree of wastage. Three actions were recommended: (1) inspection...

... stainless steels, such as alloys 304L, 304, and 304H, have essentially no ferromagnetic phases when they are in the solution annealed condition. Cold work causes a partial transformation to martensite and causes the structure to show a ferromagnetic response. The martensite reverts to austenite on annealing...

... on the results of the evaluation program. This procedure is applicable to the magnetic particle examination of ferromagnetic components using prods and dry powder with direct current (DC) according to the dry continuous inspection method. This procedure is limited to the detection of discontinuities open...

... are potential NDE options. For example, MT is useful for ferromagnetic materials but not for nonferromagnetic materials. Electrical conductivity, resistivity, and dielectric properties may be needed to determine inspection feasibility and for calibration purposes. Part thickness and density are important...

...-particle inspection (MPI) uses magnetic fields to locate surface and subsurface discontinuities in ferromagnetic materials. When the material or part to be tested is magnetized, discontinuities that generally lie transverse to the direction of the magnetic field will cause a leakage field to be formed...
