TL;DR: In this article, the effects of Mg on the chemical component and size distribution of Ti-bearing inclusions favored grain refinement of the welding induced coarse-grained heat affected zone (CGHAZ), with enhanced impact toughness in Ti-kill-ed steels, which were examined based on experimental observations and thermodynamic calculations.

TL;DR: In this paper, a hot roll bonding was carried out between commercially pure titanium TA2 and high-strength low-alloy steel Q390 using pure Nb or Mo interlayer at 950°C with a total reduction ratio of 86.7%.

TL;DR: In this article, a hot roll bonding was carried out between commercially pure titanium TA2 and high-strength low-alloy steel Q390 using no interlayer and Fe interlayer at temperatures of 850, 900, 950 and 1000°C with a total reduction ratio of 86.7%.

TL;DR: In this article, the combined effects of martensite-austenite (MA) constituent and pearlite colony on cleavage crack initiation in the simulated coarse-grained heat-affected zone (CGHAZ) of V-N-Ti microalloyed offshore platform steel under different heat inputs were investigated.

TL;DR: In this paper, the microstructure-mechanical property relationship of a Cu-bearing low-carbon high-strength low-alloy steel, subjected to a novel multistage heat treatment including quenching (Q), lamellarization (L) and tempering (T), is presented.
