Optimizing Process Parameters Using RSM to Increase the Strength and Ductility of B500BWR TMT Rebar
Journal of Engineering, Volume 2025, Issue 1, 2025.This study investigates the influence of hot working process parameters on the mechanical properties of thermomechanically treated (TMT) rebar grade B500BWR. The process involves hot rolling followed by quenching and self‐tempering. The goal is to identify the optimal parameter settings for achieving the desirable tensile strength, yield strength, and ...

Surface behavior of AISI 4140 modified with the pulsed-plasma technique
Materiali in tehnologije, 2015 In this study, the microstructure and surface properties of a low-alloy steel (AISI 4140) treated with pulsed plasma were investigated. Three different plasma-gun nozzle distances of (60, 70 and 80) mm and one battery capacity were chosen for a surface modification.

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.

EFFECTS OF CARBURIZING AND NITRIDING PROCESSES ON THE COST AND QUALITY OF GEARS PRODUCED WITH AISI 4140 AND 8620 STEELS [PDF]
Tecnologia em Metalurgia, Materiais e Mineração, 2012 This study compares the effects of nitriding and carburizing processes applied to gears subjected to contact stresses below 1300 MPa. The manufacturing cost, as well the depth of hardened layer and the distortion produced by two processes are analyzed.
