Newly released data 2011/4/1

Thermophysical properties section of NMIJ/AIST is trying to release highly-reliable thermophysical property data measured using the measuring instrument that is traceable to the national standards and their uncertainty were evaluated. We would like to give a special thanks to collaborative research institutes for agreeing to release their data.

About 20 data in all of thermal expansion coefficient, thermal expansion and specific heat capacity are newly released.

<Thermal expansion coefficient (from low temperature to room temperature)>
We released evaluated data with uncertainty information of Niobium, Tantalum, High Manganese Steel, Invar, Niobium Titanium and Titanium.
Link: Details of measurement of thermal expansion (Measurement system of the linear thermal expansion by laser interferometer from extremely low temperatures to room temperature)

<Thermal expansion (from room temperature to high temperature)>
We released the data of Pure Iron, Niobium, Cobalt, Vanadium, Tungsten, Zirconium, Tantalum, SUS316, Hafnium, Nickel, Lead and Platinum.

<Specific heat capacity>
We released evaluated data with uncertainty information of NIST SRM781 Molybdenum.
Link: Details of measurement of specific heat capacity (briefing paper for 2010 Workshops for Solid-State Thermophysical Properties Club)

Updated data matrix of each materials and propertieas by the release of new data are listed below.
