Abstract
In this paper, an analysis of the press forging process of a complex shape forming from the Ti-10V-2Fe-3Al alloy forged at the temperature of 900 degrees C was conducted. It is a high-strength titanium alloy, and, metalurgically, a near-beta alloy. A major advantage of this alloy is its good hot-die forgeability. Ti-10-2-3 is often used for near-net-shape forging applications, which include aerospace airframes hot-die and conventional forgings, and other forged parts in a wide variety of components. The preferred forging process is controlled beta forging. The characteristics of the hot deformation behaviour of Ti-10-2-3 were studied with the use of processing maps obtained on the basis of flow stress data generated in a compression test conducted over the temperature range of 800 - 1100 degrees C and strain rate from 0.01 s(-1) to 100 s(-1). For true strain equal to 0.9, one domain of flow instability was found to be present and three processing windows were isolated. The high sensitivity of the strain rate of this alloy was found. In support of processing maps, the observations of microstructures while being delivered and after deformation in controlled conditions was conducted using a Gleeble 3800 simulator, and the numerical analysis of forming the analysed alloy in industrial conditions was designed. Numerical calculations were conducted using a program based on the finite element method realized in QForm 3D. The high compatibility of numerical calculations results with the industrial test was found.
