Abstract
1. The optimal concentration of boron in alloy VZhL12B for the attainment of phase stability, the formation of a minimum amount of eutectic γ′-phase, and superior properties of 0.05–0.08%. 2. The favorable effect of boron additions is due to formation of the boride M3B2, which prevents the appearance of the embrittling σ-phase in the alloy during use, at locations where chromium and molybdenum accumulate around eutectic γ′-phase. 3. The high thermal stability of the alloy is due to the ability of the boride M3B2 to partially dissolve at high temperatures and stresses, with subsequent interaction of the boron with structural defects at interphase boundaries.
