Conclusions
-
1.
By homogenization annealing of low-alloy molybdenum alloys supersaturated with carbon that have a subgranular structure it is possible to obtain finely dispersed precipitates of carbide phase evenly distributed in the grains, with a heterogeneity factor of ∼ 1 μ.
-
2.
The structure of the alloy obtained as the result of homogenization annealing depends to a considerable extent on the annealing temperature. The optimal temperature is that at which the rate of “decomposition“ of dislocation boundaries and the rate of precipitation of particles of second phase of critical size in subgrain boundaries are comparable.
-
3.
Finely dispersed particles of second phase evenly distributed in the grains (density μ−3) that are thermodynamically stable at high temperatures stabilize the mechanical properties of the alloy with prolonged holding at high temperature (1500° for 100 h).
