A novel multiscale process simulation to predict the impact of intrinsic heat treatment on local microstructure gradients and bulk hardness of AISI 4140 manufactured by laser powder bed fusion

Virtual and Physical Prototyping, 2023
Although finite element model based process simulations for the laser powder bed fusion additive manufacturing process have become more common in the recent years, the proposed approaches are often only viable for materials without complex phase ...

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.

Wear behavior of iron boride coating on AISI 4140

Protection of Metals and Physical Chemistry of Surfaces, 2016
A new paste technique was established for making boronising coatings. This method gave iron boride coatings a unique wear and tear property something that was tested as a microstructural feature. The coats were acquired from obtained by transmission of boron molecules from ferrobor concentrates to steel surface.

Evaluation of wear and friction properties of graphite modified Lubri polylactic acid with various infill fabricated by additive manufacturing techniques

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
