International objectives towards improved resource and energy efficiency require new manufacturing processes, such as the proposed thermomechanical tangential profiled ring rolling process. A rapid cooling-down for microstructural adjustment a final calibration step via cold forming are combined into one single step. The reduction of process steps reduced number heating cycles present opportuni...

Influence of formation of surface nano/ultrafine structure using deep rolling on plasma nitriding and tribological properties of the AISI 316L stainless steel was investigated. Initially, the deep rolling process was carried out on the bar-shaped specimens at 15 cycles with 0.2 mm/s longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received...

Continuous improvements of properties for individual parts are indispensable for perpetual development of aircraft engines. Concerning casing and seal, simulation of ring rolling process is one of the most attractive tools to reduce the cost and time and to improve the properties and the reliability at the same time. In order to obtain both practical prediction accuracy and acceptable computati...

In the present study, we designed a ring rolling preform for producing a ringed product with a grooved outer circumferential surface. One of the most common defects in the profile of a ring rolling process is unfilling, which occurs when the deformation amount of product is small or the depth of the groove in the outer surface is large. To prevent unfilling, the deformation amount should be inc...
