Polymer Composites, Volume 45, Issue 17, Page 16133-16152, 10 December 2024.The Graphical Abstract is proper for publication. Abstract Three‐dimension (3D) printing technology, also known as additive manufacturing, is a manufacturing technology that creates three‐dimensional objects by depositing material layer by layer, as opposed to subtractive manufacturing methods. However, the newness of the technology brings with it many

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4607-4617, December 2024.ABSTRACT Shot peening (SP) and fine particle peening (FPP) were performed as post‐treatments on induction‐hardened and tempered AISI 4140 steels. Furthermore, the combined effects of surface characteristics including changes in surface morphology, compressive residual stress, and hardness on the fatigue limit were quantitatively examined.

International Journal of Ceramic Engineering &Science, Volume 6, Issue 6, November 2024.Abstract In this study, the role of MgB2 in composite coatings is pivotal. Electroless Ni–B plating, a current‐free chemical reduction process, deposits nickel–boron coatings. Other than MgB2, reinforcements like SiC, B4C, and so forth are used with Ni–B coatings for improved properties.

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4000-4011, November 2024.Abstract In this study, multifunction cavitation (MFC) was performed on low‐alloy steel (AISI 4140 steel) rods with different hardnesses to increase their fatigue limit. It was found that a high compressive residual stress was generated on the surface of steel rods by MFC and that the magnitude of the compressive residual stress tended to increase with
