Computer simulation of hardness and microstructure of casted steel 100Cr6
Journal Title: Archives of Materials Science and Engineering - Year 2016, Vol 78, Issue 1
Abstract
Purpose: The research purpose is to upgrade the mathematical modelling and computersimulation of casting of steel.Design/methodology/approach: Based on theoretical analyses of physical processeswhich exist in casting systems the proper mathematical model is established and computersoftware is developed.Findings: On the basis of control volume method, the algorithm for prediction of mechanicalproperties and microstructure distribution in steel casting has been developed.Research limitations/implications: The computer simulation of casting of steel isconsisted of two parts: numerical calculation of transient temperature field in process ofsolidification and cooling of casting to the final temperature, and of numerical calculation ofmechanical properties.Practical implications: The hardness and microstructures of casting has been predictedbased on CCT diagrams. Physical properties that were included in the model, such as heatconductivity coefficient, heat capacity and surface heat transfer coefficient were obtainedby the inversion method.Originality/value: The algorithm is completed to solve 3-D situation problems such as thecasting of complex cylinders, cones, spheres, etc. The established model of steel castingcan be successfully applied in the practice of casting
