摘要:This paper presents test results of mechanical properties of EN AW-AlZn5Mg1Zr and EN AWAlZn5Mg1,5CuZr aluminum alloys for various tensile strain rates.Static tests were conducted with the use of MTS 810.12 tension test machine,and dynamic tests - with RSO rotary impact test machine.The work was aimed at determination of effects of strain rate and notch geometry of specimens on their material mechanical properties and damage mechanisms.
