Effect of austempering conditions on the microstructure and mechanical properties of AISI 4340 and AISI 4140 steels

Journal of Materials Research and Technology, 2019
AISI 4340 and AISI 4140 are normally used for different structural applications in quenched and tempered state due to their high strength, high abrasion and fatigue resistance but they lack toughness. Presence of dual phase microstructure such as ferrite-

Laser Surface Remelting of AISI 4140 Steel

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In order to improve the surface wear resistance and hardness, laser remelting was used to process AISI 4140 steel. The microstructure and the Vickers hardness of surface and cross-section of those samples were studied. The results shown the laser power was one of the most important facts, which affect the enhanced hardness and ...

Wear of Tailored Forming Steels

Advanced Engineering Materials, Volume 25, Issue 13, July 2023., 2023
The wear behavior of additively welded steel cladding layers for tribologically loaded surfaces is investigated on a ball‐on‐disk tribometer. The results show that the steel–steel multimaterial specimens exhibit comparable wear behavior to conventional monolithic parts, demonstrating the potential for the use of additive manufacturing processes in ...
