Abstract
Aluminium alloys (AA) series 5000 are widely employed in engineering applications due characteristics such as high thermal conductivity, high corrosion resistance, good weldability and formability. Specifically, AA5052 is increasingly replacing steels in marine and automotive industries. Currently, these industries seek continuous improvements regarding their productive processes and product quality, avoiding issues closely related to unsuitable production operations planning. Important tools towards the adequate design of manufacturing process and related final product characteristics are the microstructural and mechanical characterization, which allow identifying conditions leading to variations in the material behavior during processing. In an effort to contribute on this matter, this work aims to evaluate the microstructural and mechanical properties of 5052-H32 aluminum alloy. Microstructural characterization is performed using scanning electron microscopy and X-ray diffraction techniques, while mechanical characterization is conducted means of tensile and hardness tests. The obtained results show that the materials microstructure is constituted by Al3Fe and Al3Mg2 intermetallic particles and Al2O3 inclusions precipitated in the aluminum matrix. Plasticity increases regarding the rolling orientation from 0° to 45° and decreases from 45° to 90°, while elasticity has an opposite behavior and hardness is not affected by the rolling direction. The mean and planar anisotropy indexes values indicate the suitability of the material by forming processing. Finally, the strength coefficient and strain hardening exponent values indicate that the alloy has lower formability than other Al alloys used in similar applications.
