Fatigue Behavior of Dissimilar Aluminum Alloy Spot Welds

Porosity Control and Fatigue Behavior in A356-T61 Aluminum Alloy

Much work has been done, in recent years, to characterize the factors that cause porosity in aluminum castings, and to analyze the impact of porosity or microstructural parameters on fatigue life. What has yet to be done is systematically separate out the effects of dendrite arm spacing and largest pore size from each other, and from the underlying chemical and process parameters that influence...

The 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...

Factors 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...

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...
