Abstract

Microstructural investigations of the new economically doped alloy SLZhS32 BR are carried out, and workpieces of single-crystal specimens are cast for mechanical tests. Thermal processing conditions are developed, workpieces are processed, specimens are made for mechanical and metallographic investigations, and metallographic investigations and strength tests are carried out. The produced alloy has creep-rupture strength σ₁₀₀¹⁰⁰⁰= 238–248 MPa at a density of 8.87 g/cm³.
