摘要：

Precipitation of secondary phases in quenched alloy Ti - 14% Mo during continuous heating at a rate of 5 K/min is studied. Using quantitative methods of analytical transmission electron microscopy and x-ray structural phase analysis in situ presence within the alloy of athermal omega-phase is established, quenched from the beta-range, whose lattice constants differ somewhat from the tabulated values. On heating there is precipitation of isothermal omega-phase with spacings approximating tabulated values, and at temperatures above 500 degrees C there is formation of alpha-phase particles within the alloy structure. The effect of precipitated second phases particles on alloy hardness is determined.
