The research focuses on the development of high-quality material composites by cold roll bonding in an XHV adequate atmosphere. By targeted preheating of the stronger composite partner below the hot forming limit, the flow stresses of the composite partners will be specifically adjusted for an easier processing control and improved microstructural and mechanical properties of the produced composite. In addition, relevant mechanisms will be analysed and advantageous parameters identified to enable in-line heat pre-treatment under XHV-adequate conditions. Complemented by a series of tests for combined (pre-)rolling under XHV-adequate conditions with subsequent rolling under normal conditions, the first step of process scaling will be taken.

研究的重点是开发高质量材料复合材料的冷轧粘接在XHV充足的气氛。通过对低于热成形极限的强复合材料进行有针对性的预热，可以调整复合材料的流动应力，从而更容易控制加工过程，改善复合材料的显微组织和力学性能。此外，还将分析相关机制并确定有利参数，以便在xhv充足的条件下进行在线热处理。通过在xhv充足条件下的联合（预）轧制和在正常条件下的后续轧制的一系列试验，将采取工艺缩放的第一步。
