【 摘 要 】

The article presents selected theoretical and experimental test results for cold forming of AlCu4MgSi aluminum alloy conducted on an oscillating die press PXW-100AAb. Cylindrical samples of aluminum alloy used in the tests were the T42 ones subjected to the process of natural ageing as well as the ones in transient W temper obtained by solution treatment. The experimental tests were supplemented with a numerical analysis based on the FEM. It was assumed in the calculations that a rigid-plastic material model, with thermal phenomena taken into account, and, additionally, the Cockroft-Latham material cracking model would be used. The obtained test results proved that additional heat treatment preceding cold forming allows for increasing the limit strain.
