Yield Strength Enhancement by Carbon Trapping in Ferrite of the Quenching and Partitioning Steel
P. Chen,P. Chen,Guodong Wang,Anna V. Ceguerra,Andrew J. Breen,Simon P. Ringer,Xiong Xiaochuan,Qi Lu,Jeff Wang,Yi Hongliang +9 more
TL;DR: In this paper, the authors proposed that carbon trapping in dislocations at the ferrite grain boundaries during partitioning process is responsible for the yield strength enhancement of ferrite, and demonstrated that carbon atoms segregating in Dislocations can increase yield strength by approximately 300 MPa.

Effect of Acicular Ferrite and Bainite in API X70 Steel Obtained After Applying a Heat Treatment on Corrosion and Cracking Behaviour
TL;DR: In this article, the effect of acicular ferrite (AF) and bainite (B) obtained by heat treatment (HT) applied to an API X70 steel on corrosion resistance and stress corrosion cracking susceptibility was evaluated through polarization curves and slow strain rate tests respectively, in NS4 solution and congenital water (CW).

Effect of Nb on improving the impact toughness of Mo-containing low-alloyed steels
TL;DR: In this paper, the impact toughness of low-alloyed Cr-Mo steels with Nb can be improved by the formation of fine Mo-rich ξ-phase carbides lining up along the boundaries.
