Special Issue Information

Dear Colleagues,

One of the most important properties of metals and alloys is their ability to deform permanently without breaking cohesion, known as plasticity. It is this property that makes possible the plastic processing of metals in processes including rolling, forging, pressing, drawing, and obtaining finished products and semi-finished products such as rods, profiles, sheets, pipes, and wires. The functional properties of structural materials, especially their mechanical characteristics, are significantly influenced by the chemical composition of the alloy, the manufacturing technology, and the heat and plastic processing used, which determine the material's crystalline structure and macro- and microstructure, as well as the presence or absence of texture. In this Special Issue, we will focus on the effect of the cold and hot plastic deformation process on changes in the structure and properties of modern and advanced metallic materials (i.e., Austenitic stainless steel–ASS, High-Strength Low-Alloy–HSLA, low-carbon high-Mn TWIP steel, high-manganese austenitic steel, non-ferrous alloys, and others). In addition, in this issue we will address the welding of advanced materials and, therefore, their joining technologies to ensure high-quality joints and high mechanical properties of the obtained joints. 

We are pleased to invite you to submit original research papers, short communications, or review articles that describe the current state of knowledge in the field of Plastic Deformation and Welding of Metallic Materials. 

Research areas may include (but are not limited to) the following:

- Characterization of deformed materials (microstructure, texture, mechanical properties, etc.).

- Characterization of welded materials (microstructure, mechanical properties, etc.).

- Welding of metallic materials.

- Advanced fusion and solid-state welding technologies of materials.

Austenitic stainless steels used in structural applications suffer from stress corrosion cracking due to residual stresses during welding. Much research is being conducted to prevent the stress corrosion cracking of austenitic steels by inducing compressive residual stresses. One method is ultrasonic shot peening (USP), which is used to apply compressive stress by modifying the mechanical properties of the material’s surface. In this study, 304L stainless steel was butt-welded by gas tungsten arc welding (GTAW) and subsequently subjected to compressive residual stress to a depth of 1 mm from the surface by a USP treatment. The influence of USP on microstructural changes in the base metal, the HAZ and weldment, and the corrosion properties was analyzed. A microstructural analysis was conducted using SEM-EDS, XRD, and EBSD methods alongside residual stress measurements. The surface and cross-sectional corrosion behavior was evaluated and analyzed using a potentiodynamic polarization test, electrochemical impedance spectroscopy (EIS) measurements, a double-loop electrochemical potentiokinetic reactivation (DL-EPR) test, and an ASTM A262 Pr. C test. The surface was deformed and roughened by the USP. The deformed areas formed crevices, and the inside of the crevices contained some cracks. The crevices and internal cracks caused pitting, which reduced the resistance of the passivation film. The cross-section was subjected to compressive residual stress to a depth of 1 mm from the surface, and the outermost area of the cross-section had fine grain refinement, forming a solid passivation film that improved the corrosion resistance.
