Mechanical Properties Analysis of Al2024 alloy Submitted to Different Aging Time and different Cold Plastic Deformation degree

Abstract

Brazilian aeronautical industries report that, due to the high mechanical properties presented commercially, AA2024-T351 alloy presents fissures and non-homogeneous deformations during the mechanical processing. This work proposes a manufacturing process capable of increasing the ductility of the material to withstand tensions during processing and a subsequent treatment to recover the mechanical strength of the alloy. The sequence of operations begins with the super-heat treatment at 415ºC 2.5 h, solubilization at 495ºC 2.0 h, mechanical conformation with a degree of area reduction from10% to 90% and artificial aging at 190ºC at times of 2, 4, 6 and 8 hours. The results allowed to obtain an operational sequence where it is possible to form the alloy in the desired component, without loss of mechanical properties and structural defects, in the shortest time possible of heat treatment, reducing the manufacturing costs and increasing productivity.

“…Later as graphene is further increased to (5%) i.e., Al-0.5C-5G we can see the reduction compared to 3% Gr in the matrix because of agglomeration due to the addition of more buttressing milieu. This is due to the capacity stentorian ability of the bolstering in the milieu material [16][17][18][19] . From Figure 7 solidity surges with the upsurge in keeping Carbon Nanotube (CNT) continual and Graphene (Gr) gratified in the factual.…”

“…Microstructure of Al 2024-T3 alloy according to the literature, it can be said that the fine-white and homogeneously distributed precipitates in the microstructure are intermetallic compounds containing Cu, Mg and elemental Al. The general microstructure (α-phase) consists of aluminum phase grains in FCC crystal structure rich in Cu and other alloying elements [36][37][38][39][40][41].…”
