Short Summary of the 17th FAST/SPS Expert Group Meeting

The 17th meeting of the expert committee "Field Assisted Sintering Technique/Spark Plasma Sintering" (chaired by its initiator Prof. Olivier Guillon and Prof. Martin Bram, both Forschungszentrum Jülich) took place on December 9th, 2020. This time, the meeting was held online. More than 50 national and international participants from industry, research institutes and universities actively participated in the meeting.

The first lecture was presented by Mr. Gerhard Weber, (Dr. Fritsch Sondermaschinen GmbH), giving an insight on FAST/SPS - sintering in industrial environments. He explained case studies in the fields of diamond tool production, brake pad manufacturing and sputter target industry.

The next lecture was given by Dr. Alessandro Fais from Italy. In his talk, he introduced the working principle of the Electro-Sinter-Forging (ESF) technology, highlighting some results related to the consolidation of different materials, current challenges and future perspective of the ESF method.

This first block of lectures was completed by Prof. Salvatore Grasso, who presented Field Assisted Material Engineering (FAME). Prof. Grasso comprehensively discussed the development related to the electric current assisted sintering technologies in the last decade and future prospects.

In the following, new members of the expert committee introduced their activities. Dr. Maik Trautmann (Chemnitz University of Technology) and Dr. Steve Siebeck (Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz) spoke about field-assisted foaming of composite powders, discussing different tool geometries and their influence on the processing of metal foams.

Dr. Bram Neirinck’s (Aerosint S.A.) talk dealt with selective powder deposition – a new concept for producing multi-material structures via FAST/SPS. In addition, he discussed the possibilities of utilizing selective powder deposition to manufacture near net shape parts by FAST/SPS.

Marco Cologna (European Commission, JRC, Karlsruhe, Germany) gave a talk about advances achieved with respect to recent applications FAST/SPS in the Nuclear Fuel Cycle.

The session was concluded by a presentation of Dr. Tarini Mishra (Forschungszentrum Jülich), talking about Flash Sintering of Gadolinium Doped Ceria – ways to scale up. He presented how different flash sintering modes, where the electrical parameters are precisely controlled, could result in homogeneous densification in large pellet shaped samples.

Prof. Olivier Guillon closed the virtual meeting announcing the 2021 meetings, planned at Fraunhofer IKTS Dresden in June 2021 as well as later in the year at Dr. Fritsch in Fellbach.

Chairman of the Workgroup Field Assisted Sintering Technology FAST/SPS
