The Effect of Shaft Diameter on Hardness Distribution and Case Harden Depth of AISI4130 Alloy Steel after Quenching

Abstract:

The objective of this study was to investigate the influence of specimen radius on the hardness of AISI 4130 steel in water-quenching process. The paper demonstrates how these parameters can affect the hardness from the surface to center of round samples. The experiment was performed and constructed relationship between hardness and geometry parameters to estimate hardness distribution for shaft diameter 55 mm and 80 mm. The relationship between hardness and radius was also constructed to predict hardness at center and corner for shaft radius 7.5-40 mm.
