The Hammer Forging of Ti-6Al-4V Alloy

In this paper, the research results of hammer forging process of titanium alloy Ti-6Al-4V are described. It is hard deformable alloy so forming details with complex shape from this alloy requires precise selection of thermomechanical parameters. Proper design of technological forging process of forging from Ti-6Al-4V alloy, taking into account the initial metal working, shape of supportive impressions, lubricants with proper tribological properties and also proper selected temperatures of tools and material allows to get the final product without defects. The numerical modelling based on the FE software QForm 3D was carried out. The distributions of temperature, effective strain and material flow kinematics were analyzed. The correctness of the modelling results was verified by the forging test performed in industrial conditions. Hammer forging tests were made in Polish forging plants. The products of good quality were obtained.
