Abstract
Purpose. To establish the regularities of the non-detachable compound formation of a thin-walled elements from the Ni-20Cr-6Al-1Ti-1Y2O3 alloy and to determine the functional condition of the soldering modes influence on the compound physical-mechanical characteristics. Methodology. The comparative analysis method has been used to find out solution for ensure reliable welding of plates. Results. For experimental studies serial and special laboratory equipment for welded and soldered processing has been used. It has been shown the modeling of temperature fields in ANSYS 18.1. It has been established that the process of vacuum soldering should take place at a temperature of 1350°C for 15-20 min; the strength of the resulting compound is 390-420 MPa when the sample is stretched. Origi- nality. For the first time it has been obtained the samples of compounds: a single plate, a model of a multiplanar sys- tem with y-shaped bridges; sample layout. Practical value. The obtained information can be used as a theoretical ba- sis for the development of the manufacturing process of the elements of the spaceship heat-shielding system.
