WebThe cost to diagnose the B14B2 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. … WebSpherical inclusions in the size range of 500 Å-l μm have been observed inside the matrix Re2Fe14B grains. Characterization by X-ray diffraction, electron microdiffraction and energy dispersive X-ray microanalysis, shows that these inclusions are f.c.c. rate earth oxides. The volume fraction of these inclusions increases with Ho content.
