Since 2007 High Temperatures-High Pressures regularly publishes invited articles selected from presentations given during the International Workshop on Subsecond Thermophysics (IWSSTP). These well-established workshops take place every three years at various locations. They are aimed to provide a forum for exchange of knowledge, experience and ideas on the latest developments and trends in the field of thermophysical property measurement. A special focus is given to measurements under extreme conditions, at high temperatures or pressures, and/or on the study of the behavior of matter under conditions close by or far away from thermodynamic equilibrium. Timescales range from milliseconds to picoseconds, necessitating rapid resistive or inductive (volume) heating, laser pulse heating, levitation techniques on ground and under microgravity, as well as other recently developed fast investigation techniques.
The 12th IWSSTP, which this present special issue is devoted to, took place from June, 3rd to June, 6th, 2019. It was a pleasure and a great privilege for me and the Institute of Materials Physics in Space of the German Aerospace Center (DLR), Cologne to organize the current event and welcome the international community as hosts.
This time, the 12th IWSSTP coincided with the 50th anniversary since the launch of High Temperatures – High Pressures which gave reason to celebrate.
