N2 - This paper presents advanced methods using the deep X-ray lithography (X-ray LIGA) and the powder metallurgy processing to fabricate imitative Stress Corrosion Crack (SCC) for electromagnetic NDE as needed to be a reference specimen. A pattern of the imitative SCC was formed by using X-ray LIGA with controllable shape and size with precise details of SU-8 material. The prepared pattern was then inserted into mixed-stainless steel and Sn powders in a soft mold by using less pressure filling method. Afterward, the specimens were sintered at 1100 °C. The results showed that these promising combined techniques can be utilized to fabricate micro sizes of the imitative SCCs. In addition, an inversion scheme was utilized to evaluate the equivalent conductivity of the specimens. The analysis results revealed that they were appropriated for desired equivalent conductivities of actual SCC detection by an eddy current testing.
