The Effects of Crossover Pores on High Temperature Bending Behavior of 3-Dimensional Braided C/SiC

Effect of mortar joint thickness on deformability in medieval stone walls

An analysis of the stone walls in Gothic cathedrals revealed that Medieval master builders varied mortar joint thicknesses from one structural member to another. This fact, which has gone largely unnoticed to date, has a considerable impact on the structural behavior of cathedrals,due to its direct effect on two funda…

Abrasive Wear Behaviour of Liquid Crystal Polymer Polyamide and Polyphenylenesulfide Polymer Composites

NewIn-situ synthesis method of magnesium matrix composites reinforced with TiC particulates

Magnesium matrix composites reinforced with TiC particulates was prepared using a new in-situ synthesis method of remelting and dilution technique. And measurements were performed on the composites. The results of x ray diffraction (XRD) analysis confirmed that TiC particulates were synthesized during the sintering pr…

High temperature oxidation behavior of AISI 304 and AISI 430 stainless steels

The oxidation behavior of AISI 304 and AISI 430 stainless steels was investigated from 1100 °C up to 1200 °C. Mössbauer spectroscopy and x ray diffraction were used to access the phase composition of the formed scales. The main crystalline phases found in the oxidized materials at temperatures above 1100 °C were hemat…

The effect of hydrogen peroxide on the electrochemical behaviour of Ti-13Nb-13Zr alloy in Hanks' solution

Titanium alloys are largely used for biomedical applications mainly due to their high corrosion resistance resulting from the protective oxide film formed on their surface. The literature, however, has pointed out discrepancies between in vitro tests and in vivo tests. These discrepancies have been ascribed to hydroge…

Electrochemical extraction of chlorides from reinforced concrete: variables affecting treatment efficiency

This paper reports the results of applying electrochemical chloride extraction (ECE) to a series of chloride-contaminated concrete specimens. Experimental conditions were varied to study the efficiency of this technique under different circumstances. The survey covered the possible relationship between efficiency and…

Technical Note: Alterations in the stone masonry of the Capitol Room of Sevilla City Hall

The main aim of this work has been to determine the causes of stone loss (small particles and one larger piece) and mortar loss in the coffered vault of the Capitol Room in the City Hall of Seville. The analyses and assays carried out during the course of this research have revealed that this masonry comprises a cover…

Residual Stress Analysis and Expansion of Plastic Zone in Simple Supported Woven Ni-Cr Reinforced Thermoplastic Matrix Composite Laminated Plates

Simulation of the solidification of pure nickel via the phase-field method

The Phase-Field method was applied to simulate the solidification of pure nickel dendrites and the results compared with those predicted by the solidification theory and with experimental data reported in the literature. The model's behavior was tested with respect to some initial and boundary conditions. For an initi…

Electrochemical behavior of Ti and Ti6Al4V in aqueous solutions of citric acid containing halides

This paper reports on an investigation of the electrochemical behavior of Ti grade 2 and Ti6Al4V alloy in aqueous citric acid solutions with pH 2.0 containing halide ions. Voltammetric studies of Ti and the alloy in citric acid, with and without chloride ions, indicate that the Ti and Ti alloy presented a passive beha…

Ternary blended cement concrete. Part I: early age properties and mechanical strength

While there is ample information in the literature on the mechanical performance and durability of concrete made with either limestone or granulated blast furnace slag,very little is known about the effect of the combined action of these two additions on concrete properties. The present paper evaluates the early stage…

Transfer and anchorage bond behaviour in self-compacting concrete

Self-compacting concretes (SCC) provide solutions to the problems facing precast concrete construction, enhancing competitiveness, reducing turnaround times and improving final product quality. SCC is fast becoming a key product for the future development of the precast pre-stressed concrete industry. The present pape…

Effect of rare earth oxide additions on oxidation behavior of AISI 304L stainless steel

AISI 304L stainless steel powder compacts containing 2 vol% high purity rare earth oxides were prepared by mixing the different powders in a vibratory mill followed by pressing. The compacts thus obtained were sintered in a vacuum furnace and isothermal oxidation measurements were carried out in a muffle furnace, in a…

Landmark Paper Index: Definition and Application to Rheological (η-) Journals

We define a Landmark Paper Index (LPI), calculate and analyze indices for all papers published in rheological journals (‘η-journals’) between 1990 and 2006. This paper offers some information about the criteria influencing the impact of publications on the (scientific) community. In opposite to the well known Impact F…
