Influence of the Cooling Regime on the Characteristics of Plasticity in the Case of Steel for Metal Structures


Abstract:
An important influence factor is the cooling speed value after the heat treatment. It is important to be chooses the optimal cooling regime because the steel can be laminate at high temperature. Another reason for the monitoring of the cooling speed and the conditions of the cooling regime is the possibility that the steel was heated at high temperature after lamination process, for plastic deformation, to realize metallic sculptures or other components used in industry. For this study we considered three groups of samples of the steel, each group had eight samples. Three different mediums for directing of the cooling process were considered. The characteristics of the plasticity and some mechanical properties of the steel have been modified. Finally, after an experimental program, a statistical model tried to demonstrate that a causal connection between two variables such as: the cooling speed (VR) and tensile elongation (A5) of the samples from steel exists. This work proposes to achieve a statistical model and it studies the possibility to improve the characteristics of the plasticity implicitly other properties of steel used for metal structures.
