Particle Based Ceramic Matrix Composites

Plenarsaal R124, Montag, 09. September 2024, 09:45 - 10.30 Uhr
The challenge to improve toughness and integrate dedicated functional properties are driving ceramic research towards the development of multi-functional materials. Integrating mechanical and functional requirements is possible in ceramic matrix composites with ceramic and/or metal secondary phases, whereas irreconcilable properties, like hardness and toughness, can only be integrated in functionally graded materials.
This presentation will focus on the development of composites reinforced with secondary phase particle additions targeting a combination of high strength, toughness and hardness along with an electrical conductivity allowing shaping by electrical discharge machining. Examples include Al2O3, ZrO2, Si3N4 or SiC matrix ceramics reinforced with transition metal carbides, nitrides or borides. Most of these composites however cannot be fully densified by means of pressureless sintering, requiring pressure assisted densification. The request for an electrically conductive composite is also beneficial during spark plasma sintering, which enables the in-situ synthesis of composites. Some potential applications of the developed composites will be illustrated such as stamping and fine blanking tools, extrusion dies, and cutting tools. Functionally graded materials form a major processing challenge. A colloidal processing case study on the development of Al2O3-ZrO2 functionally graded hip joint components will be highlighted, as well as the initial results on realising ceramic-ceramic and ceramic-metal multi-materials by means of additive manufacturing.

The Importance of international Collaboration for Sustainable Application of Refractory Materials

Plenarsaal R124, Dienstag, 10. September 2024, 09:00 - 09.45 Uhr
The Federation for International Refractory Research and Education (FIRE) has been active for nearly 20 years and has grown to the global network today representing the foremost academic institutions involved in refractory research and education along with the leading industrial companies. The mission with FIRE is to promote pre-competitive research and education in refractories and at the same time attract young talent to the industry. Its activities include, joint pre-competitive research programs, fostering student exchanges across the network, knowledge consolidation and dissemination through 2 volumes of a compendium on refractories, webinars, short courses and the very successful summer schools.
Refractories today are a global industry serving thermal process industries with H2/O2 in metallurgy/chemistry/cement industry as well as firing/sintering of ceramics including insulating materials. The biggest challenge for the refractory industry is to continue to meet the performance expectations while, at the same time, moving to a more sustainable production direction. The complexity and urgency of these technology changes, highlighted by the European Green Deal, requires a Concerted European Action on Sustainable Applications of REFractories (CESAREF). A consorted and coordinated European network with steel, refractory, raw material producers and key academic poles tackles the following key topics: efficient use of raw materials and recycling, microstructure design for increased sustainability, anticipation of hydrogen steelmaking, energy efficiency and durability. The network trains highly skilled doctoral candidates capable of communicating and disseminating their acquired knowledge.

3D Technology: Revolutionary breakthrough or deceptive mirage?

Plenarsaal R124, Dienstag, 10. September 2024, 09:45 - 10.30 Uhr

Additive Manufacturing has been around for decades, but its innovation is accelerating We propose to explore the impact of 3D printing on the world of ceramics. For researchers, this technology unleashes creativity and enables the exploration of new materials and processes. Manufacturers, on the other hand, can benefit from more flexible production and new business models with additive manufacturing.
This raises a pivotal question: will 3D printing remain at the laboratory stage, or will it find bold manufacturers to embrace it?
3D Ceram illustrates the possible perspectives of this transition, offering the opportunity to move from traditional production to advanced 3D manufacturing. The environmental implications and new horizons that are opening up, particularly through automation and Artificial Intelligence, are also addressed, highlighting the central role played by process providers.
Their responsibility in the additive manufacturing sector's development is engaged based on their ability to support customers worldwide over time with appropriate resources.
