Questions of thermomechanical parameters appointment under the semihot (warm) forging of metal preforms were considered. The international experience was analyzed as well. Economically effective thermomechanical conditions under semihot/warm forging, which is capable to provide a high complex of the mechanical properties of steel, are offered. The economical effect after the process integration to the industry was considered.

“…Rotary forging is a special technology for the plastic working of a wide variety of mechanical components such as disks, rings, flanges, and gears. 1 − 3 It has many advantages over the conventional technologies, such as requiring lower load, being shockless and noiseless, and affording better working conditions. 4 , 5 A lot of studies on the rotary forging process have been carried out, such as the mechanism of material flow, 6 , 7 the influence of key process parameters on cold rotary forging, 8 , 9 and mushroom shape formation mechanism of the workpiece during rotary forging.…”

Rotary forging was conducted for TA2 titanium samples with initial forming temperatures ranging from room temperature to 923 K. The microstructure of the samples was examined by using electron back-scattered diffraction and X-ray diffraction. The results indicate that rotary forging remarkably enhanced the formability of TA2 titanium and took a notable grain refinement effect over the whole temperature range. The theoretical calculation results indicate that enough working heat was generated during the early deformation stage to raise the temperature of the sample to above the dynamic recrystallization temperature. The deformation of titanium during rotary forging can be roughly divided into two stages as dislocation slip stage and the dynamic recrystallization stage.

“…Now-a-days rotary forging has become a substitute for conventional forging especially in case of producing thin discs and large flanges having high diameter-to-thickness ratio. Reports by Semiatin [1] and Aksenov and Kunkin [3] indicate that approximately one-quarter to one-third of all parts that are either hammer or press forged could be formed on a rotary forge, however the rotary forge applications are limited to the production of only axisymmetric parts at present.…”

The present work includes an in-depth study of microstructure and mechanical property development in a cold rotary forged component manufactured from Inconel 718 alloy. This work is pioneering in that there is no detailed study available in the literature focussing on cold rotary forging of Inconel 718. A tubular preform of 6 mm wall thickness was cold rotary forged into a 90 degree flange part followed by annealing with double aging. The present study provides a thorough analysis of microstructure, hardness and surface roughness evolution from as-received to final cold rotary forged and heat-treated condition including crystallographic texture changes occurring at different stages. The solution-annealed condition of the preform was found to be most suitable for cold rotary forging of Inconel 718. An annealing treatment followed by double-aging imparted desired properties such as homogeneous microstructure, uniform hardness distribution and improved surface roughness into the cold rotary forged Inconel 718 flange. The cold rotary forging can be a cost-effective route for manufacture of axisymmetric components with high material yield and low buy-to-fly ratio for expensive materials such as Inconel 718.
