Investigation on the Influence of Shear on Void Closure in Open‐Die Forging Processes

steel research international, Volume 93, Issue 11, November 2022., 2022
To guarantee the highest mechanical properties, internal defects such as voids must be eliminated during open‐die forging. However, models that predict void closure are generally only suitable for use in the core fiber. To overcome this limitation, an extended void closure model is presented to consider shear outside the core fiber.

Decarburization and Its Effects on the Properties of Plasma-Nitrided AISI 4140 Steel: A Review. [PDF]

Materials (Basel)
Despite the surge in plasma nitriding research, few reviews thoroughly examine how surface decarburization—occurring both before and during the treatment—affects AISI 4140 and similar steel grades. This review addresses that shortfall by providing an investigation into the decarburization process and its consequences.

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

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 ...
