Abstract.
Consequently, these materials are weak and easy to break under tensile stresses.
Therefore, when the brittle materials are employed for structural components, care has to be taken to avoid tensile stress.
Although brittle materials can endure a large compression, cracks may propagate when excessive compression is applied.

Abstract.
The key to the preparation is to develop biodegradable polyols with low molecular weight, which react with isocyanate to introduce biodegradable chain into the polyurethane.
Ionic liquids, which are noncorrosive and nonflammable organic salts comprising entirely of ions, are liquid at or near room temperature and, as consequence of their nature, show some intriguing features such as extremely low vapor pressure, high thermal stability, ability to retain liquid state over a wide temperature range and ability to dissolve many organic, inorganic and polymeric materials [8].

Abstract.
Recently, many methods have been made to develop adsorbents for desulfurization of fuels, such as activated carbons [11], mixed metal oxides [14], clays [15]and zeolite-based materials [16].
The objective of this research is to acquire a deep insight into the mechanism of adsorption desulfurization on activated carbon materials and the relationship between the oxygen content and pore structure, and to explore the influence of high temperature treatment on pore structure and surface properties of the activated carbon, and their adsorption desulfurization performance.

Keywords: Cu - Al - Mn, cold rolling, stress induced martensite, shape memory alloys.
For εP = 12 % damping increases again and a maximum in amplitude dependence of damping appears being characteristic for materials with cracks [13 - 15].
This was already reported for many materials for example in [13 - 15].
Conclusions Plastic deformation like cold rolling of Cu - Al - Mn shape memory alloys increases the volume fraction of martensite in the material.

Consequently, β-Sialon has been widely used in high temperature, automotive and aerospace industries, as engineering ceramics and refractories [2].
In the last decades, the non-isothermal thermogravimetric analysis (TGA) has been extensively used in the study of oxidation kinetics of non-oxide materials [5].
In this work, β-Sialon powders were firstly fabricated by the combined sol-gel and microwave carbothermal reduction nitridation method using Si(OC2H5)4, Al(NO3)3·9H2O and C12H22O11 as the main starting materials, and their oxidation behavior was further investigated by using the non-isothermal TG method.
The main raw materials used included Si(OC2H5)4 (analytical reagent grade, SiO2 ≥ 28wt%), Al(NO3)3·9H2O (≥ 99wt%), C2H5OH (36~38 wt%) and C12H22O11 (chemical reagent grade) powders.
