With the development of new steels and processing techniques, there have been corresponding advances in the fatigue performance of automotive components. These advances have led to increased component life and smaller power transfer systems. New processing approaches to enhance the fatigue performance of steels are re…
Generally, oxide scales formed on high Cr steels are multi-layered and the kinetics are strongly influenced by the alloy grain boundaries. In the present study, the oxidation behaviour of an austenite steel TP347 with different grain sizes was studied to identify the role of grain-boundaries in the oxidation process.…
Zinc oxide varistors are nonlinear voltage dependent ceramic resistors used to suppress and limit transient voltage surges. The work reported in this paper involves the relationship between microstructural characteristics and the varistor performance of ZnO ceramics doped with rare-earth oxides. Samples of these ceram…
The global pressure for recycling and ecological energy production increases steadily in combination with the demand of cost-effective application of materials. However, some severe corrosion problems, associated with the high internal/intergranular corrosion rates in boiler components need to be avoid. Some commercia…
Titanium alloys have several advantages over ferrous and non-ferrous metallic materials, such as high strengthto-weight ratio and excellent corrosion resistance. A blended elemental titanium powder metallurgy process has been developed to offer low cost commercial products. The process employs hydride-dehydride (HDH)…
A systematic study has been conducted to investigate the influence of a wide range of alloying elements and different processing conditions on the resistance of low-carbon steels to CO2 corrosion. Strong carbide-forming microalloying elements such as Ti, Nb and V, along with Cr additions, and different levels of Mn, S…
The objective of the present work is the study and comparison of the criteria for conformity and acceptance of the EHE (1), EN206-I (2) and ACI 318 (3) series of standards, which are in use in Spain, the European Community, the US and many Latin-American countries. As such, the paper starts with a conceptual different…
Many papers have been published on a wide range of aspects of the fundamental physics and chemistry of quenching such as: additive technology, surface rewetting, hardness distribution prediction, role of heat transfer and residual stresses, etc.1,2. However, relatively little information has been published on the appl…
The AR glass reinforcement fibres were designed to resist the alkalis from the concrete. This is the main reason for its utilisation as a short-fibre-reinforcement of mortar and concrete for the last decades. Originally, the AR glass fibre sizing was not compatible with synthetic resins, so that this type of reinforce…
It is essential to have an in-depth understanding of corrosion phenomena, from both a scientific and a technological viewpoint, in order to develop strategies that minimise the costs associated with the corrosion of materials. Looked at in this way, corrosion can be seen to be not merely an economic problem. Studies o…
A key element to improve the analytical capabilities of surface-enhanced Raman spectroscopy (SERS) resides in the performance characteristics of the SERS-active substrate. Variables such as shape, size, and homogeneous distribution of the metal nanoparticles throughout the substrate surface are important in the design…
A striking feature of nanocrystalline (NC) materials prepared by different techniques is the variation of lattice strain present in the crystallites. A simple model is proposed to account for this phenomenon, which allows the establishment of a quantitative relationship describing the dependence of the crystal lattice…
Abstract Several new interlayer-grafted derivatives of kaolinite were synthesized by esterification of inner-surface hydroxyl groups with alkanols, diols and glycol mono-ethers starting with the dimethyl sulphoxide intercalate. The derivatives were characterized by X-ray powder diffractometry, thermal analysis, Fourie…
We report the direct microscale resistance profile measurements on a symmetric thin-film electrical pulse induced resistance change (EPIR) device composed of a Pa0.7Ca0.3MnO3 (PCMO) active layer, using surface scanning Kelvin probe microscopy. The resistance switching is found to be an integration of the resistance ch…
Three types of nonlinear organization schemes for creating ringlike semiconductors have been elucidated with the self-assembly of nanocrystals in aqueous phase under one-pot conditions. The synthetic architecture is based on morphological controls of primary nanocrystals which possess an intrinsic hexagonal symmetry.…
Summary. — Rare-earth elements are of interest in several high-tech and envi-ronmental application areas, the two major ones concerning magnetic and optical devices. In the latter field, one can exploit the unique photoluminescence properties of rare-earth ions to develop novel or advanced lasers and optical amplifier…
Synthetic nacre morphologically indistinguishable from the natural archetype was synthesized with amorphous calcium carbonate precursors by confinement in the scaffold of the original insoluble nacre matrix. The precursors were generated using a synthetic polyelectrolyte highlighting the physicochemical aspects of bio…
Optical imaging technique has strong potential for sensitive cancer diagnosis, particularly at the early stage of cancer development. This is a sensitive, non-invasive, non-ionizing (clinically safe) and relatively inexpensive technique. Cancer imaging with optical technique however greatly relies upon the use of sens…
