Susceptibility to Stress Corrosion Cracking of AZ31B Magnesium Alloy by Slow Strain-Rate Technique

Prediction of corrosion rate of AZ31B magnesium alloy under salt fog environment in NaCl solution

Magnesium alloys have gained considerable interest as a material for automotive and aerospace applications due to its low density, high specific strength, and good castability. However, another considerable issue is their corrosion properties. This restricts their practical applications. In this present research, corrosion behavior of the AZ31B magnesium alloy was evaluated by conducting salt f...

Slow Strain Rate Testing to Evaluate the Susceptibility of Welded Low Alloy Steel to Environmentally Assisted Cracking

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...

Assessment of Stress Corrosion Cracking on Pipeline Steels Weldments Used in the Petroleum Industry by Slow Strain Rate Tests

Mitigation of Corrosion on Magnesium Alloy by Predesigned Surface Corrosion

Rapid corrosion of magnesium alloys is undesirable in structural and biomedical applications and a general way to control corrosion is to form a surface barrier layer isolating the bulk materials from the external environment. Herein, based on the insights gained from the anticorrosion behavior of corrosion products, a special way to mitigate aqueous corrosion is described. The concept is based...

Effect of Hydrogen on Corrosion and Stress Corrosion Cracking of AZ91 Alloy in Aqueous Solutions

The effect of hydrogen on the corrosion and stress corrosion cracking of the magnesium AZ91 alloy has been investigated in aqueous solutions. Hydrogen produced by corrosion in water diffuses into, and reacts with the Mg matrix to form hydride. Some of the hydrogen accumulates at hydride/Mg matrix (or secondary phase) interfaces as a consequence of slow hydride formation and the incompatibility ...
