These materials are typically produced in most by the techniques of Powder Metallurgy and cover a wide range of applications, such as stone processing, civil engineering, etc.
Conclusions Yield stress can be considered an important parameter to be evaluated in this study because in practice, adopting a pre-strain of 0.2%, it practically coincides with elastic limit of the material, parameter essential in any engineering project.

The Risk Measurement of the Space Launch Test Project Based on Gray Relational Analysis1 Yaodong Le1, a, Fajie Wei2,b and Anying Liu3,c 1School of Economics and Management, Beihang University, Beijing, 100191, China 2 School of Economics and Management, Beihang University, Beijing, 100191, China 3 School of Reliability and System Engineering, Beihang University, Beijing, 100191, China aleyaodong@163.com, bweifajie@buaa.edu.cn, canny1123@sohu.com Keywords: The space launch test project, Gray relational analysis, Risk measurement Abstract.
Since the various theories and methods of risk management were introduced to China from 1980’s, they were gradually applied to the project management, especially in large-scale civil engineering projects.

The strain rate sensitivity was determined with the help of dynamic uniaxial tensile tests at average engineering strain rates of 1, 10, and 100 s-1.

Influence of Microstructure on Physico-Mechanical Properties and Corrosion Resistance of Refractory Forsterite-Spinel Ceramics NGUYEN Martin1,a* and SOKOLÁŘ Radomír1,b 1Brno University of Technology, Faculty of Civil Engineering, Institute of Technology of Building Materials and Components, Veveří 331/95, 602 00 Brno, Czech Republic anguyen.m@fce.vutbr.cz, bsokolar.r@fce.vutbr.cz Keywords: Forsterite; spinel; synthesis; microstructure; corrosion resistance.
Owing to its very high melting point of 1890°C and its low reactivity with iron at high temperatures, forsterite has been largely used as a refractory lining of metallurgical furnaces and regenerators in the iron, steel and non-ferrous metals industries. [1–3] Due to the high coefficient of thermal expansion of forsterite, which closely correlates with the coefficient of metals, forsterite ceramics are also applied for ceramic-metal joints in electrotechnical engineering [4, 5].
