Study About the Influence of Cryogenic Treatment on the Impact Strength Properties of C45 Steel
Journal Title: RECENT - Year 2011, Vol 12, Issue 31
Abstract
The paper presents the influence of the subzero treatment on the impact strength properties of case steel C45. The modern processes employed to produce durable components include cryogenic treatment as well as conventional heat treatment. Metallic materials in various applications are subject to exploitation negative temperature of -10°C…-200°C. Limits of elasticity and flow resistance to plastic deformation, that in some cases and increase hardness and fatigue strength, with decreasing temperature. At low temperatures, however, the mechanical characteristics of particular importance, has tenacity, sensitivity decreased and the tendency of brittle fracture. Steels, cast iron and ferrous alloys for the cryogenic should not show (except in the smallest possible) the latter trend. The C45, behaviour of low temperature is one of the most important studies when we want to determinate the phase transformation in solid state and the results of impact strength properties of this material and this paper present some aspects of this.
