| Summary: | In the present paper, the effects of artificially produced pit-like defects00 the strength of members made of A1SI 410 Martensitic stainless steel were investigated. Compressor blades in power generation industries made of A1SI 410 stainless steel commonly suffer from pitting corrosion. Well-defined pit-like defects were artificially produced on various specimen and strength tests were conducted. A1SI 410 stainless steel microstructure shows a typical body-centered te1ragooal (bet) structure. Strength tests analysis established yield strength of 547 MPa for case I (max depth-max diameter) whereas a yield strength of 585 MPa for case 2(min depth-min diameter), In addition, strength and elongation of the artificially produced pitted tensile specimen gradually decrease with the increase of the area lost doe to artificially produced pits. |
