Yarlagadda, Prasad K., Rao, K.P., & Hawbolt, E. Bruce (1996) Hot Deformation Studies On A Low-Carbon Steel: Part 1 - Flow Curves And The Constitutive Relationship. Journal of Materials Processing Technology, 56(1-4), pp. 897-907.
In the present paper the flow stress of a plain low carbon steel at hot working conditions has been obtained using a computer controlled servo hydraulic Gleeble compression testing machine. Experiments have been conducted under both isothermal, near constant strain rate as well as varying conditions such as sudden changes in strain rate (between 0.1-8s -1) and temperature (between 900-1100°C) up to a true strain of 0.8. The experimental data on flow stress has been analyzed and it has been found that they can be adequately represented using an Arrhenius-type hyperbolic-sine relationship. Based on the analysis of the experimental results a simple constitutive equation of semi-empirical nature has been formulated for describing the flow stress as a function of strain, strain rate and temperature for isothermal conditions. The accuracy of the prediction of flow stress based on proposed constitutive equation has been tested for test.conditions other than those used for the formulation of the constitutive equation and found to be satisfactory. Also, it has been identified that the proposed constitutive equation can describe strain-hardening, dynamic recovery and dynamic recrystallization at higher strains. In addition, experimental results for varying conditions of strain rate and temperature (jump tests) are presented.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
