The present research investigates the influence of surface roughness imparted by cold finishing processes on localized corrosion resistance stainless steel. Five different alloys were studied: ferritic AISI 430, martensitic 430F, austenitic 303, 304L, and 316L. It was demonstrated that grinding process, executed previously drawn bars, leads to an improvement in according results obtained with e...

Abstract The "Gold Dust Defect" affects the surface quality of AISI 430 ferritic stainless steels. However, there is a very limited number studies focusing on it. To better understand its nature, we have combined several techniques, such as x-ray photoelectron spectroscopy, atomic force microscopy, and transmission electron in order to extract maximum structural compositional information. Our r...

Austenitic stainless steel is the most commonly used material in production of orthopedic prostheses. In this study, AISI 430 SS (0.12 wt. % C; 1 Si; Mn; 18 Cr; 0.04 P and 0.03 S) will be modified by creating austenite removing its ferromagnetic properties via high-temperature gas nitriding process. Cold rolling with various percentage reduction (30, 50, 70 %) was followed at a temperature 1200...

The Attachment Insecurity Screening Inventory (AISI) 2-5 years is a parent-report questionnaire for assessing attachment insecurity in preschoolers. Validity and reliability of the AISI 2-5 years were examined in a general sample (n = 429) and in a clinical sample (n = 71). Confirmatory factor analysis (CFA) confirmed a three-factor model of avoidant, ambivalent/resistant and disorganized attac...

in order to enhance the performance of interconnects which are used in solid oxide fuel cells (sofcs), a protective/conductive coating can be applied. in this research aisi 430 ferritic stainless steel was coated in a mn-base pack mixture by pack cementation method. in order to evaluate the oxidation behavior, isothermal oxidation was accomplished for 200 h at 800 ºc. electrical behavior was al...
