A systematic approach to understanding the role of microstructure on the mechanical response of complex multiphase materials is presented based on the "microstructure reconstruction" method of Yeong and Torquato. Low-order statistical correlation functions ...
Nanostructured materials should present a good resistance to irradiation because the large volume fraction of grain boundaries can be an important sink for radiation-induced defects. The objective of the present study is to experimentally investigate the i ...
We have investigated some anodic and cathodic transformations using boron doped diamond (BDD) electrodes. The oxidn. of a propargylic alc. as well as the arom. side chain oxidn. in water as electrolyte did not yield the desired products in high yield and s ...
Mechanisms responsible for the embrittlement of leaded "free-machining" copper alloys at intermediate temperatures (i.e. around 400 °C) are examined using a combination of microstructural and mechanical characterization. Tensile tests are conducted on pure ...
A new technique is proposed for the direct measurement of capillary forces in systems of relevance to the infiltration processing of metal matrix composites. Capable of handling melt temperatures up to 1500 K and infiltration pressures up to 20 MPa, the te ...
This paper deals with the electrochem. reactivity of B doped diamond (BDD) electrodes. A comparative study was carried out to show the influence of the presence of graphitic micro-domains upon the surface of these films. Those graphitic domains are sometim ...
The objective of this paper is to present the fundamental phenomena occurring during the scribing and subsequent fracturing process usually performed when preparing surfaces of brittle semiconductors. In the first part, an overview of nano-scratching exper ...
Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...
A study of the microstructure developing at the surface of glass fibers in a poly(vinyl acetate) (PVAc)/polyester blend is presented. Three different experimental methods are used: a technique based on the Wilhelmy method to measure the wettability of the ...
During nanoindentation measurements of thin films the formation of cracks within the film as well as of pile-up or sink-in around the indent are known to affect significantly the precision of hardness and Young's modulus values. The crack pattern in brittl ...
