the microstructure of hp stainless steel in aged and aged + solution annealed conditions and solutionized alloy 800 was characterized by optical microscopy, scanning electron microscopy (sem), and transmission electron microscopy (tem) equipped by eds. all phases present in the above condition were described. the effects of solution annealing heat treatment temperature on the microstructure, te...

In the present scenario, aerospace and automobile industries depend on lightweight materials such as magnesium aluminum alloys because of their great balance between mechanical properties weight ratio. Despite these benefits during joining process dissimilar by welding, many challenges arises. The prominent one is related to low melting points metals which make it almost impossible using conven...

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...

Abstract Ferrous alloys are employed in a range of fields, including aerospace, construction, automobiles and chemical processing. One the most used welding processes for fusion ferrous metals is gas tungsten arc (GTA) or Tungsten Inert Gas (TIG) welding. Due to lower amount penetration accomplished using only one pass, less frequent some industrial situations. Fluxes have been discovered impro...

Since welding residual stress is a major factor in the generation of Primary Water Stress Corrosion Cracking (PWSCC), it is essential to examine the welding residual stress to prevent PWSCC. In order to predict this residual stress, several artificial intelligence methods have been developed and used as a powerful tool in nuclear engineering fields. In this study, two data-based models, support...

Coupled with convection flow, multisolute dilution was investigated by an improved numerical model during laser dissimilar welding of 304 stainless steel and nickel. Thermal behavior firstly studied solidification characteristics were also analyzed. Then, dimensional analysis driving force carried out, the evolution surface tension shear stress quantitatively analyzed for a better understanding...

Friction stir welding does not involve bulk melting of the components that are joined. This has inspired attempts to exploit it for joining materials which differ in properties, chemical composition or structure, and where fusion can lead to detrimental reactions. The purpose of this special issue of Science and Technology of Welding and Joining was to assess the status of friction stir welding...
