Efecto del tiempo en el proceso de homogenizado en la extrubilidad del aluminio 6063 en la empresa Cedal

Abstract

The research carried out in the CEDAL company analyzes the changes in the mechanical and microstructural properties of the 6063 alloy and relates them to the defects present in aluminum extrusion in different batches that have been subjected to different homogenization times (4, 5 and 6 hours of support at 565oC). The report compares the values of mechanical strength, elongation, hardness, grain size and microstructural changes between the specimens before being homogenized and those specimens that have been homogenized for 4, 5 and 6 hours. In addition, given the traceability, it is possible to identify the defects present after the extrusion process and to associate them with the homogenization time, so that keeping the aluminum ingots in the homogenization oven for 5 hours at a temperature of 565oC represents the most appropriate option so that the alloy presents the best characteristics in the final product and as raw material to the extrusion process. A proposal is presented as the procedure that will guarantee the verification, control and validation of the raw material, as well as to guarantee its traceability and to associate it with the defects that occur in the extrusion process.
