Project title Setting of an ultra-fine microstructure in forged blanks by cross wedge rolling (Feinkornwalzen)
Project duration 01.02.2020 – 31.01.2022
Press release

In order to automatically determine the state of an aluminum melting furnace, the IPH develops a Preforms that can be produced by cross wedge rolling are further processed in the forging industry into a wide variety of components and are characterized by high material efficiency. The aim of the project is to identify a process window for a cross wedge rolling process by which an ultrafine microstructure can be adjusted in cylindrical blanks. The desired grain size of the rolled part should be in the ultrafine grain range. A cross wedge rolling process for mass distribution can also be connected to the cross wedge rolling process for the production of ultra-fine microstructure in order to make use of the good properties (high ductility, good formability at low temperatures) of the preforms with simultaneous material-efficient further processing.

Publications about the project

In a research project at the Institute for Integrated Production in Hanover, the process parameters for cross-wedge rolling are to be determined with which an ultrafine microstructure can be achieved in cylindrical blanks. The aim is to achieve grain sizes of the rolled part in the range of 500 nm.
