In this paper, two groups of Nb/Ti low carbon microalloyed steels (Nb-bearing and Nb-free)
were obtained through laboratorial methods. The evolution and effect of Nb/Ti-containing …

In this work, a multi-gradient ultrafine grain (GUFG) structured high strength low alloy (HSLA)
steel was successfully prepared by adopting a two-stage rolling coupling ultra-fast cooling …

Seismic anti-seismic rebar, as materials for supporting structures in large buildings, need to
have excellent mechanical properties. By increasing the Nb content and controlling the …

The Charpy impact toughness (CVN) properties of a Nb+ V microalloyed X70 steel of YS∼
540 MPa was studied at various angles with respect to the rolling direction. The …

The effects of cold rolling reduction rates and recrystallization annealing temperature on the
microstructure, texture, and anisotropic properties of high-strength low-alloy (HSLA) steel …

Hydrogen-induced mechanical degradation was evaluated in different environmental
conditions on two X70 pipeline steels having the same composition but different …

In this study, the relationship between the anisotropy of toughness and microstructure in low
carbon low alloy steel treated by quenching and tempering (QT) heat treatment was …

This paper presents the research results on the mechanical behavior of the low-carbon
rolled steel of a sea portal crane after a 33-year operation depending on the operational …

Low-cycle-fatigue behaviour (Δε t/2=±0.002 to±0.01) of a ferritic-steel (tensile strength∼ 800
MPa) strengthened with nano-meter-sized-precipitates has been examined. The selected …

Two B400B-R and B500B grade rebars were industrially produced through a Tempcore
process. The standard chemical composition of B500B grade was additionally alloyed with …
