Due to plastic deformation of metastable austenitic steel, phase transformation from γ-austenite into α’-martensite occurs. This is initiated by the formation of shear bands as product of the external stresses. By means of coupled microscopic and micromagnetic investigations, a characterization of the microstructure was carried out. In particular, this study shows the distribution of the strain-induced α’-martensite and its influence on material properties like hardness at different depths. The microstructural analyses by means of electron backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite (ca. 23 %) close to the outer specimen surface, where the plastic deformation and the direct contact with the forming tool take place. In the middle area (ca. 1.5 mm depth from the outer surface), the portion of transformed α’-martensite drops to 7 % and in the inner surface to 2 %. These results are well correlated with microhardness and micromagnetic measurements at different depths. EBSD and atomic force microscopy (AFM) were used to make a detailed characterization of the topography and degree of deformation of the shear bands. Likewise, the mechanisms of nucleation of α’-martensite were discussed. This research contributes to the development of micromagnetic sensors to monitor the evolution of properties during flow forming. This makes them more suitable for closed-loop property control, which offers possibilities for an application-oriented and more efficient production.</jats:p>"}]},{"publication":"Key Engineering Materials","abstract":[{"text":"<jats:p>The production of complex multi-functional, high-strength parts is becoming increasingly important in the industry. Especially with small batch size, the incremental flow forming processes can be advantageous. The production of parts with complex geometry and locally graded material properties currently depicts a great challenge in the flow forming process. At this point, the usage of closed-loop control for the shape and properties could be a feasible new solution. The overall aim in this project is to establish an intelligent closed-loop control system for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces in a flow forming process. To reach this goal, a novel sensor concept for online measurements of the wall thickness reduction and the martensite content during forming process is proposed. It includes the setup of a modified flow forming machine and the integration of the sensor system in the machine control. Additionally, a simulation model for the flow forming process is presented which describes the forming process with regard to the plastic workpiece deformation, the induced α’-martensite fraction, and the sensor behavior. This model was used for designing a closed-loop process control of the wall thickness reduction that was subsequently realized at the real plant including online measured feedback from the sensor system.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"quality_controlled":"1","year":"2022","date_created":"2022-11-04T08:27:33Z","publisher":"Trans Tech Publications, Ltd.","title":"Innovative Online Measurement and Modelling Approach for Property-Controlled Flow Forming Processes","type":"journal_article","status":"public","department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"user_id":"36287","_id":"33999","publication_identifier":{"issn":["1662-9795"]},"publication_status":"published","page":"862-874","intvolume":"       926","citation":{"chicago":"Kersting, Lukas, Bahman Arian, Julian Rozo Vasquez, Ansgar Trächtler, Werner Homberg, and Frank Walther. “Innovative Online Measurement and Modelling Approach for Property-Controlled Flow Forming Processes.” <i>Key Engineering Materials</i> 926 (2022): 862–74. <a href=\"https://doi.org/10.4028/p-yp2hj3\">https://doi.org/10.4028/p-yp2hj3</a>.","ieee":"L.

Hence, Bayesian optimization is precisely adapted to the application of\r\nbonding: the constraint is used to check one quality feature of the process and the use of batches leads to\r\nmore efficient experiments. Our approach is suitable to determine a feed-forward control for the bonding\r\nprocess that provides very high quality bonds without using a physical model. We also show that the quality\r\nof the Bayesian optimization based control outperforms random search as well as manual search by a user.\r\nUsing a simple prior knowledge model derived from data further improves the quality of the connection.\r\nThe Bayesian optimization approach offers the possibility to perform a sensitivity analysis of the control\r\nparameters, which allows to evaluate the influence of each control parameter on the bond quality. In summary,\r\nBayesian optimization applied to the bonding process provides an excellent opportunity to develop a feedforward\r\ncontrol without full modeling of the underlying physical processes.","lang":"eng"}],"publication":"Proceedings of the 11th International Conference on Pattern Recognition Applications and Methods (ICPRAM)","type":"conference","language":[{"iso":"eng"}],"keyword":["Bayesian optimization","Wire bonding","Feed-forward control","model-free design"],"department":[{"_id":"153"},{"_id":"880"}],"user_id":"82875","_id":"29803","page":"383-394","citation":{"ieee":"M.

In this paper information obtained from a microscopic traffic estimation using various data sources is used to feed a new developed traffic control approach. The presented method can control a traffic area with multiple traffic light systems (TLS) reacting to individual road users and pedestrians. In contrast to widespread green time extension techniques, this control selects the best phase sequence by analyzing the current traffic state reconstructed in SUMO and its predicted progress. To achieve this, the key aspect of the control strategy is to use Model Predictive Control (MPC). In order to maintain realism for real world applications, among other things, the traffic phase transitions are modelled in detail and integrated within the prediction. For the efficiency, the approach incorporates a fuzzy logic preselection of all phases reducing the computational effort. The evaluation itself is able to be easily adjusted to focus on various objectives like low occupancies, reducing waiting times and emissions, few number of phase transitions etc. determining the best switching times for the selected phases. Exemplary traffic simulations demonstrate the functionality of the MPC-based control and, in addition, some aspects under development like the real-world communication network are also discussed.","lang":"eng"}],"publication":"Communications in Computer and Information Science","keyword":["Traffic control","Traffic estimation","Real-time","MPC","Fuzzy","Isolated intersection","Networked intersection","Sensor fusion"],"language":[{"iso":"eng"}],"place":"Cham","page":"232–254","intvolume":"      1612","citation":{"ama":"Malena K, Link C, Bußemas L, Gausemeier S, Trächtler A.

This makes the method ideal for control engineering applications, because a linear system description is often assumed for this purpose. Using academic  examples, we simulatively analyze the prediction performance of the learned EDMD models and show how relevant system properties like stability, controllability, and observability are reflected by the EDMD model, which is a critical requirement for a successful control design process. Subsequently, we present our experimental results on a mechatronic test bench and evaluate the applicability to the control engineering design process.

By controlling workpiece properties during the process, beneficial effects caused by forming can be exploited and integrated in the product design. The overall goal of this investigation is to produce tailored tubular parts with a defined locally graded microstructure by means of reverse flow forming. For this purpose, the proposed system aims to control both the desired geometry of the workpiece and additionally the formation of strain-induced α′-martensite content in the metastable austenitic stainless steel AISI 304 L. The paper introduces an overall control scheme, a geometry model for describing the process and changes in the dimensions of the workpiece, as well as a material model for the process-induced formation of martensite, providing equations based on empirical data. Moreover, measurement systems providing a closed feedback loop are presented, including a novel softsensor for in-situ measurements of the martensite content."}],"status":"public","date_updated":"2023-12-15T09:39:21Z","oa":"1","author":[{"last_name":"Riepold","full_name":"Riepold, Markus","first_name":"Markus"},{"full_name":"Arian, Bahman","id":"36287","last_name":"Arian","first_name":"Bahman"},{"last_name":"Vasquez","full_name":"Vasquez, Julian Rozo","first_name":"Julian Rozo"},{"last_name":"Homberg","id":"233","full_name":"Homberg, Werner","first_name":"Werner"},{"last_name":"Walther","full_name":"Walther, Frank","first_name":"Frank"},{"full_name":"Trächtler, Ansgar","id":"552","last_name":"Trächtler","first_name":"Ansgar"}],"date_created":"2021-08-23T13:23:05Z","title":"Model approaches for closed-loop property control for flow forming","main_file_link":[{"open_access":"1"}],"doi":"10.1016/j.aime.2021.100057","publication_status":"published","quality_controlled":"1","publication_identifier":{"issn":["2666-9129"]},"year":"2021","citation":{"apa":"Riepold, M., Arian, B., Vasquez, J.

To achieve this, it is necessary to employ an appropriate process or tool design. While this will generally prove successful, it cannot, however, offset stochastic defects with local variations in material properties. Closed-loop process control represents a promising approach for a solution in this context. The state of the art involves using this approach to control geometric parameters such as a length. So far, no research or applications have been conducted with closed-loop control for microstructure and product properties. In the project on which this paper is based, the local martensite content of parts is to be adjusted in a highly precise and reproducible manner. The forming process employed is a special, property-controlled flow-forming process. A model-based controller is thus to generate corresponding correction values for the tool-path geometry and tool-path velocity on the basis of online martensite content measurements. For the controller model, it is planned to use a special process or microstructure (correlation) model. The planned paper not only describes the experimental setup but also presents results of initial experimental investigations for subsequent use in the closed-loop control of α’-martensite content during flow-forming.","lang":"eng"}]}]
