В статье рассмотрены основные подходы к оценке рисков. Авторами акцентировано внимание на нелинейном подходе к теории рисков. Предложено экономический риск...

Разработан лазерно-ультразвуковой метод определения величины остаточных напряжений в рельсах. Метод основан на лазерном возбуждении подповерхностной...

The failure or degradation of solar absorber tubes is the single largest cost factor for current parabolic trough solar power plant. The main failure reason is that there are residual stresses in the glass-to-metal joint which are generated during the cooling process of sealing. According to the...

Residual stresses of alumina thin film deposited on silicon substrate by using electron beam evaporation with oblique angle deposition (OAD) method are studied. The growth parameters that affect the residual stresses of alumina thin film, such as the substrate temperature, the deposition rate,...

Several different species of ions, Au, Fe, Ag, Ti and Si, were implanted into austenite stainless steel sheets at an energy of 3 MeV respectively. The martensite transformation induced with the ion implantation was investigated with transmission electron microscopy equipped with an energy...

The electrical and microstructural properties of a series of ZnO-based thick film varistors (TFVs) doped with 0.00, 0.02, 0.04, 0.06, 0.08, and 0.10 mol% Y2O3 were studied. It was found that sample doped with 0.08 mol% Y2O3 showed the highest potential gradient of 3159.4 V/mm with a leakage...

Microstructural evolution and fracture behavior of zirconia (ZrO2)-based thermal barrier coatings (TBCs) were investigated under thermal exposure. New ZrO2 granule with 8 wt.% yttria (Y2O3) with a deformed hollow morphology was developed through a spray drying process and employed to prepare...
