摘要：
Processes of decomposition of metastable β-phase in quenched alloys Ti – 40% Nb – (5 – 9)% Zr during aging at 400 and 500°C are studied. The time intervals of precipitation of second phases (α and ω) are determined. The effect of 5 – 9 wt.% zirconium alloying on the variation of the structure, phase composition and properties of the alloys after quenching and aging is analyzed. The impact of additional plastic deformation by rolling after the quenching on the shift of the temperature intervals of precipitation of second phases under subsequent aging of the alloys is considered.
