Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 Heat‐treated steel is widely used in industrial applications due to its high strength and other desirable mechanical qualities. Grinding, which requires a lot of power and is expensive, is typically used to harden machining. In recent times, hard machining has emerged as a viable alternative to grind in select applications.

Characterization of AISI 4140 borided steels
Applied Surface Science, 2010 The present study characterizes the surface of AISI 4140 steels exposed to the paste-boriding process. The formation of Fe2B hard coatings was obtained in the temperature range 1123–1273 K with different exposure times, using a 4 mm thick layer of boron carbide paste over the material surface.

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 ...

Mechanical Properties of Boronized AISI 316, AISI 1040, AISI 1045 and AISI 4140 Steels
Acta Physica Polonica A, 2009 In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on ...
