these two inelastic materials provides the possibility of developing residual stress fields in the composite. These stress fields could be used to apply a prestress on the ceramic phase which takes advantage of the superior mechanical response exhibited under compressive loadings. To explore the development of these r…
Adhesively bonded joints used on spacecraft are subject to thermal cycling in orbit. Effect of this ageing is investigated in terms of polyepoxy adhesive properties and corresponding assemblies. A simplified isothermal ageing model is used to understand effect of temperature and secondary vacuum. Vacuum involves the s…
Conductive hybrid coatings are an alternative for the production of multifunctional coatings, enabling wide application in industry for metal surface finishing. Recently, the use of pre-treatments using the sol-gel process has become an attractive area of study, due to its high efficacy against corrosion, low cost and…

In this study, the particle size effect of polymer-based nanocomposites is estimated quantitatively below and above the glass transition temperature through molecular dynamics (MD) simulations. The thermoelasticity and thermal expansion coefficients (CTE) at each state are calculated for various particle radii under s…
The behavior of galvanic corrosion between carbon steel and CuAlBe with Shape Memory Effect was investigated using the technique of Zero Resistance Amperometry (ZRA), in an electrolytic environment that simulates the water produced from mature oil fields. For this purpose, we used a fractional factorial design 26-2 +…
In this work, the influence of SWCNTs on electrical and mechanical performance of two epoxy resins was studied. In the first study, a small quantity of SWCNTs (0.125 wt%) was incorporated into a high-temperature aerospace-grade epoxy. After the modification with SWCNTs, the correlation between bulk properties of this…
The effect of impurity atoms on the efficiency of formation and accumulation of radiation defects in the metals and alkali halide crystals is considered. Interaction of impurities with radiation defects can both promote stabilization of the structural disorder, and suppress the radiation-defect formation. Especially t…
High temperature electrolysis of water is a well-known method of extracting hydrogen, and has reduced electrical potential requirements when compared to low temperature electrolysis. The reduction in electrical energy cost is useful when a source of high temperature steam (or sufficient waste heat) is available; howev…
The experimental data of the effect of irradiation on the decomposition of alloys and doped alkali halide crystals are presented. Depending on the composition of the solid solution and other conditions, the irradiation can both accelerate and induce the decomposition. The mechanisms and some features of the decomposit…

The study presented herein formulated 105 ternary mixture designs combining two portland cements and four blended cements with seven supplementary cementitious materials (SCM). The 105 ternary mixtures along with 12 control mixtures were tested according to ASTM C 1567 Determining the Potential Alkali-Silica Reactivit…
Given high strength-to-weight and stiffness-to-weight ratios, sandwich composite materials are continually being considered for automotive applications. Thermoplastic materials, while difficult to bond, have an increased ease of manufacture and are recyclable making them even more attractive than thermoset composites.…
Nickel and nickel based magnetostrictive alloys have been used in the many actuator and sensor applications. Though the magnetostrictive values of nickel are not very large, the good mechanical properties of nickel and nickel based alloys make them attractive in various applications. In this work, the effect of Si and…
The main kinds, properties and radiation units of measure are considered. The data on the path of the microparticles in metals and air are presented. The crystal structure of the metals and alkali halides is considered. The models of various kinds of structural defects (point, linear, volume) in crystal lattice are di…
The factors affecting the stability of solid solutions under irradiation are considered. One of these factors is the radiation-induced change of solubility. The models describing the radiation-induced decomposition of the solid solution for the different concentrations of impurities and irradiation conditions are disc…
Nitrogenated nanocrystalline diamond films were grown from hot filament reactor in CH4-Ar-H2-N2 gas mixtures. They were characterized using scanning electronic microscopy and Raman spectroscopy. Significant changes on the film surface morphologies and Raman spectra were observed due to N2 addition. Their electrochemic…
