Slow Strain Rate Testing to Evaluate the Susceptibility of Welded Low Alloy Steel to Environmentally Assisted Cracking
نویسنده
چکیده
Libya is an important oil country particularly to European countries. The combustion products of fossil fuels are causing great damage through pollution, acid rains and the greenhouse effect. Hydrogen can be stored in three different ways, as a gas, as liquid, as a material and metal hydrides. Low alloy steels have been widely used in different scale welded structures. The mechanical properties were determined with the slow strain rate test in air and in artificial seawater environment under cathodic polarization to produced hydrogen. The slight decrease in fracture energy and reduction in area at current densities in artificial seawater in comparison with the values measured in air were observed. Index Terms — hydrogen storage, low alloy steel, welded steel, slow strain rate test (SSRT).

Corrosion behavior of dissimilar welded joint between Inconel 617 alloy and A387-Gr.11 low-alloy steel
In this study, Inconel 617 alloy was welded to A387-Gr.11 low-alloy steel using ER309L filler metal via gas tungsten arc welding (GTAW). First, the corrosion behavior of Inconel 617, A387-Gr, and the weld metal was evaluated by the Tafel polarization test and electrochemical impedance spectroscopy (EIS) in acidic (H2SO4), neutral (NaCl), and combined (H2SO4 + NaCl) solution at ambient temperatu...

The varestraint cracking test was carried out to assess the hot cracking tendency of alloy 800 at different welding conditions and augmented strain levels. The test results revealed that the hot cracking susceptibility of alloy 800 increases with increasing the heat input and augmented strain levels. This emphasizes the role of constraint either internally induced or externally applied to the w...

HOT CRACK FORMATION IN PURE CU AND CU-30%ZN ALLOY DURING IN SITU SOLIDIFICATION
The hot cracking susceptibility can be determined by establishing the transition temperature between brittle and ductile fracture at high temperature tensile testing of in situ solidified samples. High temperature tensile properties were determined for commercial cathodic pure Cu and Cu- 30%Zn alloy. The transition temperatures for pure Cu and Cu-30%Zn were evaluated from ultimate tensile stres...
