Investigation of Influence of Microstructure on FH32 Steel Corrosion Properties using Gleeble Simulation of Heat-Affected Zone and Electrochemical Methods

International Journal of Electrochemical Science, 2019
The corrosion behavior was investigated for each heat-affected zone (HAZ) comprising a FH32 steel immersed in 3.5% NaCl solutions. To research the corrosion behavior of each HAZ sub-region, HAZ thermo-mechanical simulations were performed prior to the ...

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Corrosion Behavior of Galvannealed Steel

Journal of the Metal Finishing Society of Japan, 1970
Corrosion behavior of galvannealed steel was studied under various corrosive circumstances and was compared with that of galvanized or electrogalvanized steel.The results obtained were as follows:1) The corrosion rate of galvannealed steel was lower than those of other zinc plated steels.2) The coating layer of the galvannealed steel was composed of Fe-

Study on Electrochemical Behavior at a Room and High Temperature at 700 °C Corrosion of Austenite, Ferrite, and Duplex Stainless Steels

Metals
The stainless-steel phase of austenite, ferrite, and duplex was affected by the high temperature corrosion. So, the study of corrosion behavior in high temperatures at 700 °C is important because it is connected to life and maintenance. Various stainless

Corrosion Behavior of Ti-6Al-4V Alloys

International Journal of Electrochemical Science, 2012
The alloy Ti-6Al-4V has been considered ideal for implant applications. Electrochemical tests were made to analyze their resistance and predictability to corrosion from green dust samples, SPS (Spark Plasma Sintering) samples and commercial alloying. The

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Control of Magnesium Alloy Corrosion through the Use of Engineered Intermetallics [PDF]

, 2014
The low density and high relative strength of Mg alloys means they can offer engineering benefits over steels or Al alloys. However, the susceptibility of Mg alloys to corrosion has limited their exploitation and restricted their use to more benign ...
