The addition of boron(B) is frequently adopted to increase the hardenability of bainitic steels. Although it is well known that B can retard the bainitic transformation kinetics, it is still not clear how the B affe...
In low carbon microalloyed steels (C 〈 0.1%), the content of V, Nb and Ti affects the phases transformation kinetic during cooling in the rolling process. The final microstructure determines the required mechanical...

The δ-ferrite to γ-austenite phase transformation process of low carbon steel was observed in-situ under a confocal scanning laser microscope and the influence of manganese and chromium on the migration of δ/γ int...
Strain ageing in steel was first observed during the 19th century when the maximum load carrying capacity of a test piece was increased after it had been retested following a previous series of testing in a plastic ra...

The coarsened grain boundaries (GBs) with vein-like morphology frequently appear in the nitrogen diffusion layer of nitrocarburized carbon steels. The electron probe X-ray microanalysis shows that such vein-like GBs...
The purpose of this study was to describe the roles of microstructure types and grain boundary characteristics in fatigue crack propagation behavior in ferrite-pearlite steel and ferrite-bainite steel.The ferrite-bain...
To research the effect of Zr addition on inhibiting austenite grain growth of Ti-bearing low carbon steels, two steels with different Zr contents were prepared using a laboratory vacuum induction furnace. The performa...
To study the effect of Mg addition on inhibiting weld heat affected zones (HAZ) austenite grain growth of Ti-bearing low carbon steels, two steels with and without Mg treated were prepared using a laboratory vacuum....
