We have synthesized CexZr1–xO2 solid solutions via the thermal decomposition of xerogels of different compositions prepared by drying appropriate hydrosols. The synthesized materials have been characterized by thermal analysis, X-ray diffraction, and Raman spectroscopy. The results demonstrate that the solid solutions are formed at relatively low temperatures (450–600°C). The CexZr1–xO2 samples with...
The article discusses results of experimental investigations into creep deformation and long-term strength of copper tubular specimens tested under constant tensile strength in combination with torque at 264°C. The complex stress state is considered where normal and shear stresses make an equal contribution to the maximum shear stress. Velocity-strain tensors of creep and time to rupture are calculated...
