This article provides an overview of the influence welding parameters and filler material on changes in heat-affected zone (HAZ) thermo-mechanically controlled processed (TMCP) steel welded joints. The research focused evaluating effect heat input cooling rate width soft zone, which significantly affects mechanical properties negative is more pronounced as thickness decreases. Therefore, object...

High‐energy synchrotron X‐ray small‐angle scattering (SAXS) is used to study the precipitate development during hot rolling and cooling of a commercial Ti–Nb micro‐alloyed, high‐strength, low‐alloy (HSLA) steel. To precipitation conditions, Gleeble dilatometer trials are made. Samples then studied at room temperature using SAXS in conjunction with transmission electron microscopy (TEM). TEM det...

In order to study the problem of surface fluctuations and slag entrapment, the nail board experiment and simulation computation method was used to optimize the method for measuring liquid level characteristics in mold. The influence of steel nails diameter and the distance between steel nails on the measurement results was studied. The height of the liquid surface and the surface velocity at di...

Continuous cooling transformation (CCT) diagrams of base metals are common in welding. They can be built using physical or numerical simulations, each with advantages and limitations. However, those not usual for weld metal, considering its variable composition due to the dilution into metal. Wire Arc Additive Manufacturing (WAAM) is a distinctive case which interest materials comparable raises...

Ratcheting deformation in association with bulk texture evolution HSLA steel is studied this investigation. The cyclic behaviors and damage modes of the specimens are obtained at room temperature, employing asymmetric stress-controlled tests under various combinations mean stress amplitudes. Bulk measurements done adopting an X-ray diffraction analysis. results exhibit increase strain accumulat...

A recent advance in corrosion-resistance technology overcomes the problem of steel corrosion in CO2enriched environments. At an inhibitor concentration of 10 M, the inhibition efficiency exceeded 98% where the steel corrosion rate is decreased by a factor of at least 100.
