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.

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 ...
