In this study, the coarse grained heat affected zone (CGHAZ) of Cu-containing/free steels was simulated at various heat inputs by thermal simulator. A comparative study was conducted to reveal the role of Cu addition and...
Hydrogen embrittlement (HE) has arisen as a critical issue for the development of high strength steel. The austenite and Cu-rich precipitates can provide stable trapping sites for diffusible hydrogen, and thus improved t...
PurposeThe purpose of this paper is to study the effect of chromium content on the microstructure and corrosion resistance of Ni-Cr coating. Design/methodology/approachNi-Cr coating was prepared by pulse current electrod...

In this work, the feasibility of using "grain boundary engineering" to reduce the susceptibility to hydrogen embrittlement in a low carbon low alloy steel was examined. By adding Cu element, the fraction of random grain ...
This study used the electrochemical hydrogen permeation test and the slow strain rate tensile (SSRT) test to examine the impact of Cu addition on hydrogen embrittlement (HE) in a low carbon high strength steel. The follo...
Understanding the martensitic transformation mechanism is of critical importance to control martensitic transformations and hence retained austenite. Linear defects reported in a previous study can provide nucleation sit...

The effect of welding and postweld heat treatment on the microstructural characteristics and mechanical properties of a Cu-containing low-carbon low-alloy steel was studied. The obtained results indicated that ferrite, b...
A good strength-toughness combination is difficult to be obtained in welded joint of low carbon low alloy steel. In this work, a new idea was proposed to improve the strength and toughness of welded joint by strengthenin...
Using Cr-bearing low-alloy steel is an effective preventive measure for marine structures, as it offers superior corrosion resistance when compared to plain carbon steel. However, it remains unclear how quenching and tem...
Hydrogen embrittlement (HE) has arisen as a critical issue for the development of high strength steel. The austenite and Cu-rich precipitates can provide stable trapping sites for diffusible hydrogen, and thus improved t...
