Diagrams of conventional yield strength and elongation of alloy V-1341T are plotted. The effect of the temperature and duration of exposure in isothermal quenching on the composition and morphology of the products of decomposition of the solid solution of the alloy after artificial aging is studied. Transmission electron microscopy is used to show that at a high temperature (400°C) and long isothermal hold the dominant inclusions in the structure of the alloy are coarse lamellar β- and Q-phases. Lowering of the temperature and shortening of the isothermal hold reduces the formation of coarse lath precipitates of β′-phase on the dispersoid and boundaries of grains and cells and yields numerous fine inclusions of a hardening β′-phase inside the grains after aging.

Notes
Inclusions of aluminides of transition metals. As a rule, their sizes exceed the sizes of the inclusions of hardening phases by an order of magnitude or more and are hard to dissolve; the dispersoids raise the temperature of the start of recrystallization and decelerate the latter.
