Abstract:

The paper presents experimental results that concern hydromechanical bulging of copper axisymmetric components whose relative wall thickness was S0/D= 0.045. The specimens used in investigations were segments of copper tubes having the outer diameter D= 22 mm and wall thickness S0 = 1 mm. In the paper, the deformation ratio of material was defined as the relative upsetting ratio triangle I/l(0) (where triangle I - the punch displacement, l(0) - the initial length of tube). The investigations aimed to determine the impact of the upsetting ratio on microhardness in different zones of hydromechanically bulged axisymmetric components. The measurements of microhardness were taken with the Matsuzawa Seiki Co. MMT-X3 Vickers micro-hardness tester. The paper gives the comparison of the microhardness distributions in longitudinal sections of hydromechanically bulged copper axisymmetric components with different relative ratios triangle I/l(0)= 0.054 divided by.109.
