We study the influence of the modes of vacuum soldering of thin sheets made of Ni–20Cr–6Al–1Ti–1Y2O3 alloy on the mechanical properties of the obtained joints. It is shown that, in the case of soldering with a finely divided mixture of nickel, tungsten, and boron powders at a temperature of 1350°С with subsequent holding for 20 min in a vacuum of 10–3 Pa, the strength of the joint of up to 320 MPa is attained. We also deduce the equations connecting the ultimate strength of the joint and temperature strains in thin sheets with the soldering conditions.
