One of the most critical problems related to welding is occurrence Hydrogen-Induced Cracking (HIC), and despite all efforts made mitigate this defect, it remains present in modern industry. Although Gapped Bead-on-Plate (G-BOP) test one practical methods for assessing susceptibility HIC, use a thick plate as base metal (BM) restricts its application. Considering that many materials, such High-S...

High strength low alloy steel (HSLA DOCOL 500 LA) is utilized in the automotive structure because of its superior qualities such as good fatigue resistance, a high strength-to-weight ratio, assisting reducing weight vehicle, increasing fuel efficiency and lower CO2 emissions. Resistance Spot Welding (RSW) most welding technique that used to join automobile parts together. This study investigate...

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...

The formation of precipitates during thermal processing of microalloyed steels greatly influences their mechanical properties. Precipitation behavior varies with steel composition and temperature history and can lead to beneficial grain refinement or detrimental transverse surface cracks. This work presents an efficient computational model of equilibrium precipitation of oxides, sulfides, nitri...

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...
