General Project Description
A project concept is based on the assumption that all microstructural and thermo-mechanical phenomena occurring during an incremental forging process and a subsequent heat treatment can be efficiently and precisely controlled in a real time by a dedicated online calculation system. To achieve this, the integration of many individual machines and devices in the production cell with a digital twin of the process (including relevant calculation models) is necessary. The equipment has to work in parallel with monitoring of an actual workpiece geometry and temperature profile. Based on these actual data, the system will quickly determine model deformation strategy for the subsequent forging or decide to reheat a workpiece. After forging, the system will determine parameters of cooling and the nanobainitic transformation. Due to the high-speed high-volume data transfer, that is necessary but a common programmable logic controller (PLC) cannot handle, a fast fuzzy logic controller (FLC) on additional workstation will be applied. The comprehensive material investigations and numerical simulations are needed for parametrisation of the calculation models and for defining the FLC functioning. The factors, which must be taken into consideration by the online calculation system, are listed in figure below (ordered as they appear in the process chain).
The state of the art is that the phenomenon of accelerating bainitic transformation for non-nanobainite steels can be obtained by application of external stress – this constitutes the starting technology readiness on the first level. The defined main objective of the project combines three different scale of consideration of this issue. The micro-scale approach (characterization of the material subjected to specific tests) will provide the knowledge necessary to formulate conditions of forging and nanobainitic transformation process, and thus to achieve the TRL2. The meso-scale approach is going to prove the concept, both analytically and experimentally (TRL3) while the macro-scale approach will bring the TRL4 – a technology validated in laboratory conditions. The application of tension or compression stresses during bainite transformation of large forged parts can be problematic. However, torsional shear stress can be simply applied. With regard to the technology under consideration, pure shear state of stress was not considered due to the lack of sufficient available knowledge about the issue. This stress state gives the opportunity to separate the volumetric change and transformation induced plasticity and a chance of essential understanding of Gibbs energy balance due to the mechanical stabilization of austenite (high dislocation density), stress induced transformation and chemical driving force. Forgeability of high carbon steels like nanobainite steels is limited due to their susceptibility to cracking, therefore properly determined and applied hermomechanical processing parameters are essential for successful design of forging cycles. For controlling and predicting the flow behaviour of the material during hot deformation carried out at various combinations of temperatures and strain rates, processing maps based on DMM theory can be developed. Applying processing maps to predict microstructural behaviour of hot formed material and defining the combination of processing parameters, such strain, temperature, and strain rate, which are the most beneficial for processing of the analysed material. The flow behaviour and microstructural changes of various alloys, as well as the development of these materials processing windows based on DMM theory have been presented in many recent publications.
