Evaluation of microstructure and mechanical properties of 410NiMo as an overlay layer on low alloy steel
The aim of this study is to reach an increased service life for parts using in sour environment by weld overlaying process. In this investigation, two successive layers of ER410NiMo were clad on low alloy steel substrates. To reduce the likelihood of Hydrogen Induced Cracking (HIC) and producing stable hydrogen traps, Post Weld Heat Treatment (PWHT) was conducted. Microstructural analysis, X-ra...

Classification of Rust Grades on Steel Surfaces
Selecting most representative features among a huge feature set is considered in this paper. One feature extraction and five feature selection algorithms are tested on features obtained form steel surfaces. Two new feature selection algorithms are introduced in this paper. Performance measure for feature selection algorithms is also introduced as a new method to select the best performing featu...
متن کاملThe Evaluation of Corrosion Behavior of AISI 347 Stainless Steel to ASTM A335 Low Alloy Steel Dissimilar Welds
In the present study, the corrosion behavior of AISI 347 austenitic stainless steel to ASTM A335 low alloy steel dissimilar joint was investigated. For this purpose, two filler metals, ER309L and ERNiCr-3, were selected to be used during the gas tungsten arc welding process. To investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solu...
