Análise compativa dos efeitos dos passes de trefilação nas propriedades mecânicas e textura do aço SAE 1008 trefilado.

Abstract

The production of rebar and industrial wires to be made available for civil construction can be carried out by various processes of mechanical conformation, either hot or cold. However, today the industrial market demands maximum efficiency of its processes with the objective of generating products with the highest quality index and with lower cost. Therefore, the cold drawing process has been a very chosen production line, due to its high performance and stability to obtain CA-60 rebar and drawn products. Rebar is produced in accordance with quality requirements and properties that must meet national and international regulatory standards. To meet these requirements, studies of process improvement and stability, and knowledge of the mechanical, chemical and metallurgical properties of steels used as raw material for these products are required. The present work uses the techniques of optical microscopy to select the microstructure of the drawn products after the drawing pass. It used the microhardness measurement technique to understand the mechanical behavior of drawn samples, in the process passes and texture analysis techniques to verify orientation of the steel already formed.
