Microstructural Evolution in Friction Stir Welding of Dissimilar AA6061 and AA5182-H34 Alloys and Impact on Residual Stress, Material Flow, and Intermetallic Formation

Microstructural Evolution and Mechanical Behavior of Al-Added Medium-Mn Steel Under Cold Rolling: Role of Austenite Stability and Ferrite Deformation

Role of grain size in governing the mechanical response in friction-stir-welded high-aluminum low-density ferrite steel

The susceptibility of high-Al ferritic steels to thermal cracking and microstructural coarsening during fusion welding restricts their practical implementation. To address this challenge, high-quality joints of Fe–10Al alloy were successfully fabricated by friction stir welding (FSW) under ultra-low rotation (80 r/min)...

Aging-Induced Microstructural Evolution and Fracture Mechanisms of 35Cr45NiNb Alloy Under High-Temperature Tensile Deformation

Centrifugally cast 35Cr45NiNb alloy has been widely employed in ethylene-cracking furnace tubes owing to its excellent carburization and creep resistance. However, the influence of microstructural degradation and temperature on its high-temperature tensile behavior remains poorly investigated. In this study, an acceler...

Multiscale microstructural characteristics of quenched Fe50Co50 alloy and their effects on hot deformation behavior

Mechanisms Governing the Microstructural Evolution and Comprehensive Properties in Dissimilar 2024-5083 Aluminum Alloys TIG Welded Joints by Filler Wire Selection and Post-Weld Heat Treatment

Comparative Study of the Microstructure, Local Elemental Composition, Microhardness, and Dry-Sliding Friction Behavior of Co-Cr-W, Fe-Mn-C, and Fe-Cr-Ni-Mn GTAW Deposits on 09G2S Steel

This study systematically evaluates the microstructural characteristics, cross-sectional microhardness profiles, and dry sliding friction dynamics of Stoodite 6-M, AISI 1065-type (Np-65G, GOST 10543-98), and AISI 307-type stainless steel (Sv-08Cr20Ni9Mn7Ti, GOST 2246-70) coatings deposited on 09G2S low-alloy steel via...
