Workshop on Ultra High Temperature Ceramics for Thermo-structural applications

Indian Institute of Science, Bangalore, India (December 14, 2015)

Dear participants,

We thank all the participants and speaker for attending this workshop on UHTCs at IISc Bangalore. We had a number of speakers as listed here for UHTC-Workshop-IISc.

Please find here the pictures from workshop.

The past few decades have seen phenomenal research on Ultra High Temperature Ceramics (UHTCs), which are commonly defined as materials with very high melting temperatures (~3273 K) and ability to perform under extreme thermal environments. The adverse environmental effects include detrimental effects of high temperature, chemical reactions, mechanical stresses and radiation. In particular, a significant part of the research has been motivated by material needs for hypersonic aerospace application. For example, atmospheric re-entry vehicles, rockets and scramjet powered air-breathing hypersonic cruise vehicles primarily encounter high pressures and heat flux on the leading edges due to air stagnation and shock waves. Also the respective propulsion systems experience high temperature exothermic combustion reactions to produce thrust.

The trajectories for hypersonic space vehicles demand high thermal resistance for the base material to sustain operating temperatures in range 1873-2673 K. These conditions are beyond the capabilities of many engineering ceramics and have motivated researchers to pursue the development of UHTCs.

Recent research is also focused on the development of Hafnium and Zirconium based boride ceramics using advanced ceramic processing techniques for leading edge sections of hypersonic vehicles which experience extreme thermo-mechanical loading. Novel additives are being added to the ceramics to enhance oxidation resistance and thermo-mechanical properties.

This requires an in-depth understanding of the structural stability of the ceramic by evaluating micro-structural characteristics, determination of high temperature mechanical properties, study of shock-material interaction under different experimental conditions (shock wave velocity, number of pulses, environment and pulse duration) etc.

In order to address these critical issues and share research perspectives on development of UHTCs, a one day workshop on "Ultra High Temperature Ceramics" is being organized. The leading experts in the field will deliver classroom lectures and research oriented talks on UHTC development.

A special session -"Listen to Corporate R & D" will give an opportunity for industry academia interaction.

This workshop will be very useful for the young researchers and attendees will learn about the latest cutting edge research in the area of ceramics. The interaction with experts will provide valuable perspective in the field for active researchers. The workshop is being organized by "Centre of Excellence in Hypersonics".

Register here for workshop by December 8, 2015.

A brain stroming session on Ultra High Temperature Ceramics would be organized in IISc Bangalore. It is hoped that the proposed brainstorming session IMPRINT IISC UHTC would act as an effective platform to take this important initiative to the next level in a more inclusive manner.
