Study of concrete behaviour under fire has really increased since the occurence of several fires in tunnels such as the Chunnel or the Mont-Blanc tunnel. Fire...

The isothermal steady-state creep behavior of a M5® thin sheet alloy in a vacuum environment was investigated in the (α+β) temperature, low-stress (1-10MPa) range. To...

The study of the behaviour of concrete at high temperatures is of great importance to determine the stability and strength of concrete structures in fire conditions....

In aeronautics, electrical systems progressively replace mechanical and hydraulic control systems. If the electronics can stand the absence of cooling, the immediate...

In this document, we present ou study about the conception and realization of VMOS and Schottky and JBS Diodes on Silicon Carbide. This work allowed us optimize and...

I applied UV resonant Raman spectroscopy (UVRRS) to an ‘in situ’ study of carbon materials at very hight temperature (> 2000 K) or at high pressure (< 1 GPa).The...

The strength of metals, and therefore their maximum operating temperature, can be improvedby oxide dispersion strengthening (ODS). Numerous research studies are...

Chromia-former alloy are mainly used for high temperature applications. Their ability to form a protective thermal oxide scale allows reducing oxidation kinetics of...

Within the working program of CEN TC336 WG1 (Bituminous Binders) a round robin test has been performed on the fracture toughness test for bituminous binders...

Delayed ettringite formation in concrete is likely to lead to swelling and cracking in structures which have undergone eartly age heating to a temperature of over...

Currently, improving energy efficiency becomes a main challenge for all industrial energy systems. This challenge involves an improved recovery of wasted heat...

In avionic applications, semiconductor devices can be placed on the engine with an ambient temperature about 200°C and thermal cycling from -55°C to 200°C in the worst...

Molten fluorides are used in Molten Salt Reactors MSR such as the non moderated fast reactor MSFR, where the molten salt LiF-ThF4 is the fuel and the coolant. The...
