Abstract
Many of the mechanical properties of steel can be improved under controlled sequence of heating and cooling to modify their properties and to meet the desired engineering applications. In this study, the effect of heat treatment cycles (hardening, normalizing, annealing, tempering and recrystallization) on the mechanical properties of CSN 12050 carbon steel have been studied. The aim of the study of this paper is to enhance the ease of machinability for CSN 12050 carbon steel products and to achieve the ultimate goal of product sustainability optimization. The treated and untreated samples change in properties is examined using standard methods. Spectro test TXC25 machine model number 2010, Vickers Hardness tester (HV), and WP310 universal material tester is used to analyze chemical composition and mechanical properties of the specimens respectively. The standard mathematical equations are used to calculate the experimental results of mean values for the test samples of HV and the stress-strain values obtained from the tensile test; later converted to true stress-strain values. Results showed that the mechanical properties of CSN 12050 carbon steel can be changed and improved through annealing and recrystallization process for the ease of machinability. Moreover, the enhanced mechanical properties of CSN 12050 carbon steel can be enlighten the goal of product sustainability through the achieved ease of machinability in dry turning condition.
