Conclusions
-
1.
We investigated the effect of annealing 1 h at 400–1400°C on the mechanical properties of transverse and longitudinal samples and on the microstructure of molybdenum alloy sheet (alloyed with carbon and titanium).
-
2.
The formation of second phase in molybdenum and selection of the optimal heat treatment conditions make it possible to obtain a high plasticity.
-
3.
The optimal heat treatment to increase the plasticity of the material investigated is annealing at 1100°C for 1 h, which corresponds to the initial recrystallization temperature of the sheet investigated.
-
4.
The formation of carbide phase in molybdenum prevents the development of recrystallization processes.
