چکیده مقاله
Dual phase steels DPS are being increasingly used by automotive industries to achieve weight reduction and fuel saving DPS have a composite type microstructure consisting of a hard second phase martensite embedded in a ductile matrix ferrite It is therefore possible to obtain combination of good ductility and high strength Determination of phase percentages is a key factor in achieving the proper mechanical behavior of DPS This can be evaluated by the Eddy current testing ECT , nondestructively ECT is one of the oldest methods of non destructive testing but the most modern application of ECT is in microstructural inspections ECT can inspect all parts in the shortest possible time in a production line In this work influence of different ferritemartensite percentages on the output signals of ECT was studied by using Fourier transformation Higher martensite percentage decreases the magnetic permeability of the material and results in the decrease in ECT outputs
