Aluminum Alloys: from Processing to Service

Presenter: Assoc. Prof. Dr. Cecilia Poletti, 
Graz University of Technology - Institute of Materials Science, Joining and Forming

High-performance aluminum-based products require the use of many and different industrial routes. Aluminum alloys are used in lightweight components, packaging and structures due to their high specific strength and stiffness, as well as their high corrosion resistance. They can also be creep resistant at moderate temperatures. The alloys undergo complex processing paths to become a product. Once the product is in service, they support thermal/mechanical static or cyclic loads. Whether during production or in service, the exposure of the alloys to thermal and mechanical loading modify their microstructure. Furthermore, the performance of the material is a function of its microstructure. In this webinar, Dr. Poletti will give an overview of 1) thermo-mechanical testing at the laboratory scale to understand and describe the interrelation of microstructures and loads, and 2) the use of these findings to design high-performance products.

Material Characterisation and Forging Simulations Focused on Workpiece Forming Behaviour and Tool Fatigue 

Presenters: Mr. Dipl. Ing. Maiwand Hootak and Mr. Christoph Kock, M. Sc.
Institute of Forming Technology and Machines, Leibniz Universität Hannover,  Department of Material Characterisation and Simulation

The use of modern production techniques and innovative processes as well as the pursuit of future-oriented solutions characterise both large and increasingly small and medium-sized companies.

As a practice-oriented institute, the IFUM is concerned not only with basic research but also with the investigation of current problems in forming technology from industry. The philosophy of the IFUM is to take a holistic view of the processes. In a forging process, for example, both the flow behaviour of the workpiece as well as the service life of the tools are of particular importance. Over the last decades, FE simulation has proven to be a helpful tool for process analysis and optimisation. Particularly the material data used for the simulations have a decisive influence on the quality of the simulation. The Gleeble 3800 as an all-rounder in the field of material characterisation, on the one hand enables the flow properties of the workpiece material to be recorded. These can be determined for wide temperature ranges and under consideration of the forming speed. On the other hand, the fatigue behaviour of the tool material can be investigated closely related to the real physical loads. Of particular importance in the field of forging are not only mechanical low cycle fatigue (LCF) effects, but also thermo-mechanical fatigue (TMF) effects in which mechanical and thermal loads are superimposed.

Flow Localization Studies in Titanium Alloys

Presenter: Ricardo Henrique Buzolin, Graz University of Technology

Description:  During thermomechanical processing, flow instability leads to further damage in the alloy. Flow defects mainly include adiabatic shear band, wedge crack, void, and flow localization, and the flow localization is sensitive to the processing conditions, preferably observed for high strain rates, low temperature and very large strains. In order to obtain optimized processing parameters for industrial processing, these defects should be predicted and controlled.

Flow models developed for Titanium alloys were developed and validated using hot compression and hot torsion experiments with a Gleeble. Additionally, a special geometry was designed to promote flow localization during hot compression. This design can cause severe plastic deformation, i.e., high strain rate and localized strain on the sample and be used to investigate the flow localization in Titanium alloys. The flow localization parameters were programmed in a Fortran subroutine and implemented into FEM simulation to predict flow localization during the hot deformation.

Real-Time In-Situ Sensing of Microstructure Evolution using Laser Ultrasonics (LUMet) during Gleeble Simulations

Description: Dr. Thomas Garcin and Dr. Brian Allen will present an overview of the laser ultrasonic system that can be coupled with a Gleeble. Laser-ultrasonics is a technology that enables non-contact ultrasonic measurements, using lasers to generate and detect ultrasound pulses. Unlike other ultrasonic technologies, it can be used on hot materials up to any temperature because there is no physical contact. Therefore, it is ideally suited for in-situ studies of solid metallic or ceramic materials up to their melting point.

Days and weeks of metallurgical studies yielding a few measurements on quenched samples can often be replaced by a single in-situ laser-ultrasonic test, yielding hundreds of measurements in real time. Including in-situ measurement of recrystallization, grain growth, grain size, phase transitions and elastic constants.

Laboratory Supported Technology Development for Metal Forming

Presenter: Dr.-Ing. Grzegorz Korpała,  TU Bergakademie Freiberg

Description: When developing new products, the option to try out the innovative idea on a small scale is crucial. In metal processing, the chain from the melt to the finished product is long and has many process parameters. It is impossible to try them all, and the decision-makers in industrial production are often only able to draw on their experience when developing new technologies. An alternative is the evaluation and validation utilizing small scale experiments - through experimental simulation using Gleeble test equipment.

With data from experiments and microstructure analysis, new processes can be designed efficiently and effectively. Using the example of high-strength low-alloyed steels with retained austenite, we will present the advantages of Gleeble equipment in evaluating various process parameters along the entire production chain. These include the temperature ranges of continuous casting, the hot rolling strategy and temperature control during cooling. The developed technology was tested in a pilot plant in laboratory scale and then implemented in large-scale production. The successful project resulted in a patent and will be discussed during the webinar.

Forming and hot stamping operations with presentations from FAU Erlangen and Imperial College London 

Material Characterisation for Improved Process Layout of Forming Operations
Engineer Prof. Dr.-Ing. habil. Marion Merklein, FAU, Erlangen
Description: Professor Marion Merklein is head of the Institute of Manufacturing Technology (LFT) at the Friedrich-Alexander-Universität Erlangen-Nürnberg in Germany and has many years of experience with Gleeble systems. In her presentation, she will give a comprehensive overview of the possibilities for using temperature-dependent material characterisation in sheet metal and bulk metal forming. The temperature-dependent material behaviour can be modeled based on experimental material parameters, which improves numerical analysis and therefore process design. One of the current research topics at the institute is the investigation of correlations between the process temperature and the forming behaviour of high strain hardening materials for the manufacturing of self-piercing rivets. Another focus is on the characterisation of boron-manganese steel alloys for improving the design of hot stamping processes. In particular, the measurement of phase transformation is a key factor, which is analysed by the LUMet system.

Using the Gleeble to Study Cracking in Welds - Guest Speaker: John C. Lippold, Professor Emeritus The Ohio State University, Columbus, OH USA

Description: The “Gleeble” was originally developed to study metallurgical behavior and cracking associated with the heat-affected zone (HAZ) of welds. The hot ductility test was developed in the 1950s and is still widely used today to study liquation-related and solid-state cracking in the HAZ of structural materials. This presentation briefly reviewed the basic mechanisms that cause cracking in welds and highlighted tests developed using the Gleeble that can be used to evaluate susceptibility to these forms of cracking. Specifically, the 1) hot ductility, 2) strain-to-fracture, and 3) reheat cracking tests were described.
