AN EVALUATION OF THERMAL STABILITY IN DISSIMILAR WELDS BETWEEN 310 STAINLESS STEEL AND ALLOY 657
Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...
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...
متن کاملFactors Affecting Weldability Improvement of Dissimilar Welds of Aged HP Stainless Steel and Alloy 800
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...

متن کاملEffects of Nb on the Microstructure and Elevated-Temperature Mechanical Properties of Alloy 690-SUS 304L Dissimilar Welds
The purpose of this paper was to investigate the effects of Nb on the microstructure and elevated-temperature mechanical properties of Alloy 690-SUS 304L dissimilar welds. The results show that the welds were dominant with dendrites and interdendritic phases. In the low Nb welds, the main interdendritic phases were Nb-rich and Al-Ti-rich phases. Cr-carbides were precipitated along the grain bou...
