Gleeble WEbinar Series 

An interactive online meeting place for researchers to discuss how the Gleeble can help solve material challenges. 

 

 

As we all adapt to the challenges of working remotely, it is important to stay connected. To better support and empower Gleeble users, DSI is hosting a series of interactive Gleeble discussions. We invite you to join us.

Each webinar will focus on different topics, ranging from specific training and best practices to applications and research presentations. Our goal will be to keep each meeting under an hour with a short presentation by one of our experts, followed by Q&A if time permits.

We look forward to connecting with you soon.  If you have any questions, or ideas for topics that you would like covered during a webinar, please don't hesitate to contact us. (info@Gleeble.com)

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.

Characterisation of Thermal-Mechanical Properties of Materials at Hot Stamping Conditions 
By Professor Jianguo Lin and Dr Zhutao Shao, Imperial College London 
Description: Over the last 10 years, Prof Lin’s team at Imperial College London has developed new experimental methods using the Gleeble to characterise thermal-mechanical properties of materials at hot stamping conditions. In this webinar, Prof Lin will present case studies on how Gleeble and innovative fixtures are used to generate thermal-mechanical data of materials, including stress-strain curves and forming limit diagrams at high temperatures, by uni-axial and multi-axial tests under hot stamping conditions. The uniformity of temperature control and the accuracy of data collection and data post-processing will also be discussed.

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

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.

Gleeble Webinar Series - Guest Speaker Dr. Carl Slater from WMG on Gleeble Case Studies at Warwick

Episode 9 in the Gleeble Webinar Series featured a guest presentation by Dr. Carl Slater from the University of Warwick, UK. Dr. Slater provided an introduction to the Advanced Steel Research Centre, and presented a range of case studies on how Gleeble systems fit within their rapid alloys production suite and how they use Gleeble equipment to simulate the steel making process. Case studies range from next generation ultra-high temperature forming/forging, liquid inclusion - liquid steel deformation, recrystallisation optimisation and understanding the impact of aspects such as segregation on downstream processing.

Additionally, Dr Slater shared some of the modelling and past experiences that help get the most out of Gleeble systems and allows high quality metallurgical assessment of samples post-deformation.

Dr. Slater is a Senior Research Fellow in the Advanced Steel Processing Group at the Warwick Manufacturing Group (WMG) at the University of Warwick, UK and has been working with Gleeble systems for over 10 years. WMG currently operates a Gleeble HDS-V40, a Gleeble 3800 as well as Torsion and Strip Annealing Mobile Conversion Units (MCUs).
