Abstract

In this work, the effect of the torsion process angle of twist and distance from the center of cylindrical bars on the microhardness profile of annealed AISI 1045 steel was studied. 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.

扭转作用下退火AISI 1045钢圆柱棒显微硬度分布预测模型

本文研究了扭转工艺中扭转角和圆柱棒中心距对退火后AISI 1045钢显微硬度分布的影响。结果表明:合金的显微硬度随参数的增加而增加，硬化与加工过程引起的塑性变形有关，而与组织转变无关。基于实验结果，通过方差分析(ANOVA-Pareto analysis)验证了在所有研究参数中，捻度是影响最大的控制因素(59.35%)。最后，提出了一种基于扭转过程的显微硬度预测模型。

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
