SPES Target Group 2007SPES Target Group 2007Materials are mainly characterised at room temperature
What are These Properties Due To?What are These Properties Due To?
A lack of data for mechanical and thermal parameters is present mainly at high temperature (≥ 2000 °C)
There is lack of an Experimental Set-up able to measure Mechanical and Thermal Properties under these conditions
