The formation of the compositional structure of the eutectic alloys upon receipt of GTE blades

In a review article the authors provide information about the development of the technology of directional solidification patterns and GTE blades with the first experimental steps to test the technology of casting of blades in the factory. The section presents data on change of chemical composition, structure and properties of the height of samples of alloys of the system γ/γ'-MeС as well as on technological and design fea-tures of equipment for the implementation of the solidification of alloys of type ВКЛС. The article is useful for students and young employees VIAM.

High-heatresistant waterproof coverings for a heat-shielding material on the base of quartz fiber

The overview material have presented on development, characteristic and use for the orbiter thermal protection elements waterproof systems on base silicon oligomers. Emphases is spared to development of ways of interflight waterproof theatment. Operational efficiency hydrophobic-coated tiles on the base of superfine quartz fiber (TZMK-10 and TZMK-25) is confirmed with positive results of postflight control of hydrophobic coatings of the heat-protective elements dismantled from returned flight vehicles.

The effect of superplasticity in mullite–zirconia polydisperse ceramic with grain size larger then 10 mkm

The flexure deformation of ceramic mullite-based samples modified by zirconia, was investigated in this work at elevated temperatures. The effects of superplasticity and elastic afterwork were found to exist at definite conditions. The explanation of these facts based upon the structure of the material. The recommendations for application and modification of such materials are presented in the paper.
