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.

Mechanical Properties of Boronized AISI 316, AISI 1040, AISI 1045 and AISI 4140 Steels [PDF]
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 ...

Experimental Study of Mechanical Properties of AISI 1045, AISI 1053 and AISI 4140 Steels
International Journal of Engineering and Advanced Technology, 2020 AISI 1045, AISI 1053 and AISI 4140 are the mostly used material for axle shaft of a vehicle. The comparative study of these materials definitely will help in selection of appropriate material for required condition. AISI 4140 has shown greater Young’s modulus, yield strength and tensile strength, but moderate ductility is observed. The lesser ductility

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 ...
