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.
