Description
This project aims to qualify the heat treatment cycle for a Ti 6Al 4V (Grade F5) component produced by forging and ring rolling, in order to ensure compliance with the mechanical properties and microstructural requirements. The ring (OD 720 mm x WT 17 mm x H 885 mm) has been manufactured for particle physics research, as a part of an accelerator beam system.
A structured manufacturing and testing program was developed to identify the most suitable heat treatment cycle capable of providing the required strength, ductility, and a homogeneous equiaxed α+β structure. Forged blank was sectioned into multiple sectors, each subjected to different heat treatment cycles involving solution treatment and aging at various temperatures under controlled conditions.
The heat-treated samples were subsequently subjected to tensile testing, Charpy impact testing, and metallographic examination, according to applicable standard code (ASTM, SAE AMS), in order to assess the influence of heat treatment parameters on the final material properties.
An optimal heat treatment cycle was selected, based on a solution treatment temperature followed by aging, guaranteeing adeguate isotropy of mechanical properties and compliance with microstructural requirements.
The project concludes with the definition of the heat treatment process to be used for components manufacturing, guaranteeing full compliance with the specified technical requirements and ensuring a homogeneous equiaxed α β microstructure of the final product.
