A Rotary Compression Process for Producing Titanium Alloy Ti6Al4V Shafts

Article Preview

Abstract:

The paper reports selected results of the research on a rotary compression method for producing a hollow driving shaft used in a helicopter’s rear gear. The tests were performed on two types of material: steel grade 42CrMo4 (Polish Standard: 40 HM) and titanium alloy Ti6Al4V. The first part of the research involved performing a numerical analysis by the finite element method to determine an optimal range of parameters of the rotary compression process. The numerical results were then verified in experimental tests using a machine designed by the authors of this paper. The preliminary experimental results confirm that hollow parts made of steel and titanium alloys can be formed by rotary compression. The results also offer prospects for further research on this problem.
