Abstract

The work aims to explore the forging process and related parameters suitable for 2014 aluminum alloy. Forging tests were conducted on 2014 aluminum alloy extruded bars using different forging parameters. The forging ratios were selected as 7.5, 5, and 2.5, the forging temperature as 370, 400, and 430 ℃, and the forging rates as 1 mm/s and 10 mm/s. After the tests, microstructure observation and mechanical property tests were carried out. The analysis showed that under the same other parameters, the grain size of the forged piece first decreased and then increased with the increase of the forging ratio and forging temperature and the mechanical properties of the forged piece first increased and then decreased with the increase of the forging ratio and forging temperature. When the forging rate increased from 1 mm/s to 10 mm/s, there was no obvious change in the grain size of the forged piece, and the mechanical properties slightly decreased. A suitable forging scheme was obtained. Through the comparison of microstructure and mechanical properties under different forging parameters, when the forging ratio is 5, the forging temperature is 400 ℃, and the forging rate is 1 mm/s, the tensile strength of the forged piece reaches 512.5 MPa, the yield strength reaches 471.5 MPa, and the elongation reaches 11%, with good comprehensive performance.
