..., external debris, and so on. Analysis at microscopic levels provides information about the nature of inclusions, phases, and surface layers. Several cases of service failures are known to have been caused by the presence of deleterious inclusions from which cracks start in the component and propagate...

... information about the impedance of the coil. This is a complex quantity, which measures the amplitude and phase of the coil current. Certain directional movements in the vector point on the screen representing phase changes between coil current and voltage are associated with well-defined effects...

... intermetallic alloy compositions may form, depending on the phase diagram of the component metals. These intermetallic alloys may have varying mechanical strength depending upon the stoichiometry. Shorting between features can occur if the process and design rules are not optimized. Some eutectic systems...
