Third‐generation SiC fibers [High Nicalon S ( HNS ) and Tyranno SA 3 Ty – 3)] were studied by X‐ray diffraction transmission electron microscopy (TEM) after heat treatments in neutral atmosphere up to 1900°C. The microstructural changes both materials determined using a modified Hall–Williamson method introducing an anisotropy parameter taking into account the high density of planar defects. exhibit significant modifications coherent domains CDD size, which drastically increases from 24 70...
The Jules Horowitz Reactor (JHR) is a new Material Testing (MTR) currently under construction at CEA Cadarache research center in the south of France.It will represent major infrastructure for scientific studies dealing with material and fuel behavior irradiation (and consequently identified this purpose within various European road maps forums; ESFRI, SNETP…).The reactor also contribute to medical Isotope production.The perform R&D programs optimization present generation Nuclear Power...
Titanium matrix composites (TMC's) are attractive materials for aeronautical applications because of their superior mechanical performance at high temperature combined to low density. Due critical machinability, the direct metal deposition (DMD) laser technique appears be a flexible generating rather complex 3D TMC shapes. In this study, considering Ti-6Al-4V titanium matrix, and TiC reinforcements with different powder sizes, walls have been manufactured, in order find out optimal DMD...
Ni-based heat resistant fibres were used for reinforcing Al-based matrices. The goal was to improve the high-temperature mechanical properties of matrix while keeping a good ductility material, thanks ductile nature fibres. In order prevent reaction when liquid Al comes into contact with during processing composites by squeeze casting, it found beneficial passivate oxidation before infiltration. optimise composite, as far conditions are concerned, tensile tests have been performed on...
