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...

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...

High-strength low alloy (HSLA) S500MC steel is widely used for chassis components, structural parts, and pressure vessels. In this study, the effects of heat input during automatic gas tungsten arc welding (GTAW) on microstructure mechanical properties thermomechanically controlled processed (TMP) were investigated. A butt joint configuration was used, performed in autogenous mode. Six differen...
