Abstract

Aluminimum as a non-ferrous metal has recently been increasingly used, among others, it is easy to work with, has sufficient hardness and is resistant to corrosion. Heat treatment (heat treatment) on aluminum is a process of controlled heating and cooling of the material with the intention of changing the mechanical properties of the material. This study aims to determine the effect of heat treatment on the microstructure, hardness and attractiveness of type 2014 aluminum. This study aims to determine the effect of heat treatment on the microstructure, tensile test and ductility of type 2014 aluminum. The results showed that the results of the microstructure test of the raw material had evenly distributed grains. Meanwhile, materials with heat treatment by artificial aging 150°C have small granules with a large number and are closely spaced. In materials with heat treatment artificial aging 350°C, it can be seen that the grain shape is bigger and grain boundaries are not evenly distributed. In the raw material tensile test showed a tensile strength of 297,6 MPa, the tensile test with a temperature variation of the artificial aging 150°C showed a tensile strength of 268,3 MPa and the tensile test of the artificial aging temperature variation was 350°C. indicates a maximum tensile stress of 271,7 MPa. Raw material shows a higher tensile strength, possibly the effect of strain hardening is higher than the effect of artificial aging on specimens subjected to heat treatment. In the raw material tensile test showed a strain value of 26%, the artificial aging temperature variation of 150°C was 34%, and the artificial aging temperature variation of 350°C was 36%. The results of the tensile test of the three specimens showed that the specimens that were artificial aging at 350°C had the highest ductility marked with a strain value of 36%.
