The results showed that the microhardness increase with the evaluated parameters and the hardening is related to the plastic deformation caused by the process rather than by microstructural transformations. Based on the experimental results, ANOVA-Pareto analysis was conducted proving that the angle of twist is the most influential control factor (59.35 %) among the parameters investigated. Finally, a model to predict the microhardness profile from the torsion process is presented. 2018 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43060744009 https://www.redalyc.org/journal/430/43060744009/ https://www.redalyc.org/journal/430/43060744009/html/ https://www.redalyc.org/journal/430/43060744009/43060744009.epub https://www.redalyc.org/journal/430/43060744009/movil 10.17533/udea.redin.n89a09 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.89 |
