Thermo-mechanical controlled processing (TMCP) is employed to obtain the required level of mechanical properties contemporary high-strength low-alloy (HSLA) steel plates utilized for gas and oil pipeline production. The strength, deformation behavior resistance formation propagation running fractures are mainly determined by its microstructure crystallographic texture. These formed as a result ...

The effect of hydrogen charging on the lattice dilation in an ASTM A710-HSLA steel specimen was studied using neutron diffraction. First, spatially-resolved strain measurements were made on a pre-cracked steel double cantilever beam specimen under a constant crack opening displacement (COD). Measurements were made at the crack tip region for in-plane and throughthickness lattice strains. Then, ...

• An HSLA steel was designed with the Fe 2 SiTi phase as its major strengthening phase. The Heusler phase, SiTi, can act grain refiner and precipitation strengthener. Precipitation behavior of compound is affected by Nb partitioning. Record high vol% nanosized precipitates lead to record hardness. remarkable combination strength, toughness, weldability that characterizes high-strength low-alloy...

Wire and arc additive manufacturing (WAAM) has been attracting industrial attention due to its high productivity flexibility. However, fatigue life data of WAAM HSLA steel is scarce. In this study, the mechanical properties thin-walled parts fabricated by were assessed via non-destructive destructive testing, providing a comprehensive analysis on material’s behaviour. The conditions have more p...

Mechanical properties as well crack resistance and stress corrosion cracking (SCC) parameters of ultralow-carbon martensite steels (ULMS) type 05H2G2B HSLA pipe steel 10G2FB with a different structures depending on processing are investigated. It is shown that despite higher strength level, SCC ULMS 25–30% than for ferrite-perlite structure close to this subjected quenching tempering.

generaly pressure vessels should withstand internal and external pressures in the form of static or periodic stresses. if the application of such a vessel requires the lowest possible weight, the fracture mechanics approach may be considened in design procedure in order to obtain the minimum wall thickness. in this work the thickness of the vessel wall was determined using k values and smallest...
