“…It can be seen that the distribution of PEEQ is similar with the distribution of shearing strain R shown in Fig. 4(a), while small grain 03008-p. 4 ICNFT 2015 sizes with uniform distribution are also found after rolling-spinning process. These illustrate that large shearing deformation would result in large PEEQ and small grains, which is also found in other literatures [5,6].…”

Abstract. In this work, an analytical study of the macroscopic deformation and microstructure evolution of Ti-6Al-2Zr-1Mo-1V alloys during rolling-spinning forming process was performed by developing Finite Element (FE) modeling using the ABAQUS/Explicit platform. The developed FE model was validated by comparing with experimental results. To investigate the shearing deformation during rolling-spinning process, representative nodes were selected in the FE model. The shearing strains of these nodes were obtained by modeling. The influence of shearing deformation in rollingspinning forming process on microstructures was also analyzed. An optimal selection of process parameters was obtained to achieve better microstructure.

Aluminum alloy rings are widely used in aerospace, energy, petrochemical, and equipment applications. The loss of roundness often occurs because of the weak rigidity and unstable plasticity of aluminum alloy rings. Therefore, an online measurement technique for the roundness of aluminum alloy rings is critical for ensuring the processing quality of aluminum alloy rings. In this paper, an online roundness measurement method based on the laser ranging principle and improved particle swarm optimization (IPSO) is proposed with the aid of the rotation of the ring during the rolling process. First, the distance from the outer surface of the ring to the laser rangefinder was measured using a triangular laser rangefinder with the help of the rotation of the ring in the rolling process. Second, the distance data were denoized using an improved Kalman filter algorithm to reduce the influence of random noise on the measurement results. Finally, the roundness and geometric center were evaluated using the IPSO algorithm combined with the minimum zone circle (MZC) method and compared with the results obtained using the standard particle swarm optimization (PSO) algorithm, genetic algorithm (GA), and least square (LS) algorithm. The experimental results show that the roundness measured by the IPSO algorithm is less than 0.06 mm, demonstrating better performance in the roundness evaluation. The measurement method for roundness proposed in this paper is suitable for the online evaluation of large aluminum alloy rings, avoiding the influence of ring size on roundness measurement.

“…Firstly, the constitutive equation of the material used for the bearing ring manufacture is crucial to study the deformation and microstructure evolution of bearings. At present, the high temperature flow stress strain relation, austenite grain growth behaviour, volume fraction and grain size of the recrystallization are still the most important research points for the constitutive equation of the material.The mechanical conditions of rolling forming and the rules of geometric formation of bearing rings are also important and widely studied such as ring rolling theory [6,7], rolling forming process [8], process tooling [9], and forming equipment [10]. Moreover, many studies revealed the evolution rules of grain refinement, content and stability of retained austenite, and micro texture of bearing rings in ring rolling [11][12][13].…”

Ring rolling is a process for creating seamless ring-shaped components using specialized equipment and forming process because of its technological superiorities of high quality, high efficiency and low consuming in energies and materials [1]. According to the international trend of cooperative control of the geometric accuracy and microstructure performance in ring rolling, rolling forming criteria such as biting-in condition, plastic penetrating condition, and plastic deformation were considered comprehensively to manufacture the bearing rings [2,3]. The evolution rules of grain refinement, plastic damage, and texture of bearing ring in ring rolling compatible with the rolling forming criteria are required for the cooperative control of the geometric accuracy and microstructure performance [4,5].To realize the cooperative control of the geometric accuracy and microstructure performance of the bearing ring, several rules of the bearing ring formation need to be revealed. Firstly, the constitutive equation of the material used for the bearing ring manufacture is crucial to study the deformation and microstructure evolution of bearings. At present, the high temperature flow stress strain relation, austenite grain growth behaviour, volume fraction and grain size of the recrystallization are still the most important research points for the constitutive equation of the material.The mechanical conditions of rolling forming and the rules of geometric formation of bearing rings are also important and widely studied such as ring rolling theory [6,7], rolling forming process [8], process tooling [9], and forming equipment [10]. Moreover, many studies revealed the evolution rules of grain refinement, content and stability of retained austenite, and micro texture of bearing rings in ring rolling [11][12][13]. The effect mechanism of the rolling process parameters on the microstructure evolution and mechanical properties of bearing rings is also established [14,15]. Thirdly, some studies reported how the heat treatment process effects the microstructure evolution and mechanical properties of bearing rings [16,17].The above research results could hardly provide the optimal rolling technical route to realize the cooperative control of the geometric accuracy and microstructure performance of bearing rings. Further experimental and theoretical studies and numerical calculation may be needed for establishing the quantitative correlation mechanism of rolling technical route with geometric formation, fine crystalline microstructure and high toughness of bearing rings.Further, it is important to form the cooperative control mechanism of ring rolling process and heat treatment process to obtain the fine crystalline microstructure and high toughness of bearing rings. Future studies should be carried on along the above ideas to solve the optimal ring rolling-heat treatment route realizing the cooperative control of the geometric accuracy and microstructure performance of bearing rings.
