“…The weight loss at higher temperatures may be attributed to the binder burnout. [30][31][32] In order to get good microwave dielectric properties after sintering the tape, the organic additives have to be removed prior to densification. 33 If a fast heating rate is employed, chances are there for the formation of cracks or bubbles and the delamination of stacked layers of the tape.…”

“…High thermal conductivity combined with low coefficient of thermal expansion (CTE) heat-sinks has played an important role in achieving high-performance and high reliability for electronic devices and modules [1][2][3][4][5][6]. Next generation heat sink materials, which are different kinds of thermally adapted materials, have already been suggested and some have been tested on C/C, Cu/diamond, and Cu/ CNF.…”

We have successfully fabricated highly densified aluminum (Al)-diamond composite materials by a simple hot press method. The thermal conductivity of the Al-diamond composite materials was measured. These materials had different types, sizes and fractions of diamond. These obtained values were discussed based on theoretically calculated values. The thermal conductivity of the composite materials, measured by LaserFlash method, was found to have slightly increased compared to that of pure bulk Al. The obtained microstructures of the composite materials showed a lot of cleavage existing in the interface between the Al matrix and the diamond particles, which led to the low increment of the thermal conductivity. Moreover, Al-diamond bulk materials with different sintering temperatures in solid state, liquid phase, and transient region between solid and liquid of Al, have been synthesized.

“…Nanostructured refractory metals, such as nanostructured tungsten (W), offer a great potential for applications in critical conditions such as aerospace, electronics, lighting and medicine [1][2][3][4] due to their high melting point, good mechanical and physical properties [5][6][7]. Ion beam sputtering techniques employing a multilayer elaboration process is used in this work to fabricate nanostructured W thin films.…”

“…The method consists in sputtering tungsten and copper (two immiscible metals) alternatively on polyimide substrates with the control of the thickness of each sub-layer in the nanometre range [8]. The obtained composites present interesting properties including good conductivity (thermal and electrical), enhanced mechanical properties (high strength of W combined with improved ductility of Cu) [1,[9][10] and a flexible polymer substrate for use in technological applications such as sensors and stretchable microelectronics components [11][12][13]. Given the complex microstructure of the nanostructured materials due to the small grain size, strong crystallographic texture, high density of defects and significant grain boundary areas [14][15][16][17], their mechanical behaviour is particularly affected and not well understood yet.…”

This paper reports on the mechanical behaviour of nanostructured W/Cu thin films deposited on Kapton ® under controlled biaxial loadings thanks to a biaxial testing device developed on DiffAbs beamline at SOLEIL synchrotron (Saint-Aubin, France). In situ tensile tests were carried out combining 2D synchrotron x-ray diffraction (XRD) and digital-image correlation (DIC) techniques. First, the elastic behaviour of the composite metallic film -polymeric substrate was investigated under equi-biaxial and non-equibiaxial loading conditions. The results show that the strain measurements (in the crystalline film by XRD and the substrate by DIC) match to within 10 -4 . This result demonstrates the full transmission of strains in the elastic domain through the film-substrate interface and thus a good adhesion of the thin film to the substrate. The second part of the paper deals with higher strains response under equi-biaxial tensile tests. The elastic limit of the nanostructured W/Cu thin films was determined at the bifurcation point between strains obtained by XRD and DIC. Deformation mechanisms such as strain localisation and film fragmentation are proposed.
