The production of reliable metallic high-performance components is of central importance for energy and transport systems, mechanical and plant engineering and the infrastructure. Components that require high reliability and durability often necessitate manufacturing by metal forming. Forged high-performance components form the basis of technical innovations in energy and transport systems. Formed sheet metal components combine lightweight construction, crash safety and recyclability in vehicle construction. However, forming processes are predominantly open-loop-controlled processes with respect to product properties, i.e. in the forming process, no measurement of the property-determining microstructure and no feedback on the process settings takes place. This involves numerous disadvantages. If forming processes cannot adjust to fluctuations in the process and in the workpiece properties, long development phases for new materials and products, time-consuming post-processing and the production of scrap must be accepted. Increasing demands on resource efficiency and sustainability require the avoidance of scrap production and reinforce the need for closed-loop property-controlled forming processes, in which product shape and properties are set within predetermined tolerances despite unavoidable fluctuations. The challenges for the development of property-controlled forming processes result from the fact that the effect of the tool on the workpiece is highly non-linear and distributed over time and place. For property-control, forming processes must therefore be understood as spatially distributed and temporally variable systems and examined for their controllability. The priority program 2183 aims to lay the scientific foundations for property-controlled forming processes in close interdisciplinary cooperation between metal forming and materials, measurement and control engineering. For metal forming, the cooperation with control engineering creates the possibility of designing controllable forming systems in a structured way and of taking into account the sensors and actuators required for the property control in the system design. Since the microstructure cannot be observed directly in the entire workpiece during the forming process, materials and measurement engineering must develop robust measurements systems and observers that reliably estimate the microstructural state from measurable variables in dynamic measurements. The collaboration is expected to provide a fundamental insight into the design of resilient, microstructure- and property-controlled forming processes.

生产可靠的高性能金属部件对于能源和运输系统、机械和设备工程以及基础设施至关重要。需要高可靠性和耐久性的部件通常需要通过金属成形来制造。锻造高性能部件是能源和运输系统技术创新的基础。成形金属板部件联合收割机了轻质结构、碰撞安全性和车辆结构中的可回收性。然而，成形工艺在产品性能方面主要是开环控制工艺，即在成形工艺中，不进行性能决定性微观结构的测量，也不进行工艺设置的反馈。这涉及许多缺点。如果成形工艺不能适应工艺和工件性能的波动，那么必须接受新材料和产品的长期开发阶段、耗时的后处理和废料的产生。对资源效率和可持续性的日益增长的需求要求避免废料生产，并加强了对闭环性能控制成型工艺的需求，其中产品形状和性能被设置在预定的公差内，尽管不可避免的波动。性能控制成形工艺的发展面临的挑战来自于这样一个事实，即工具对工件的影响是高度非线性的，并且随时间和地点而分布。因此，对于性能控制，成形过程必须被理解为空间分布和时间可变的系统，并检查其可控性。优先计划2183旨在为金属成形与材料、测量和控制工程之间的密切跨学科合作奠定性能控制成形工艺的科学基础。对于金属成形，与控制工程的合作创造了以结构化的方式设计可控成形系统以及在系统设计中考虑性能控制所需的传感器和执行器的可能性。由于在成形过程中不能直接观察整个工件的微观结构，因此材料和测量工程必须开发强大的测量系统和观测器，以便从动态测量中的可测量变量可靠地估计微观结构状态。预计此次合作将为弹性，微观结构和性能控制的成形工艺设计提供基本见解。
