Conclusions

  1. 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. 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. 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. 4.

    The formation of carbide phase in molybdenum prevents the development of recrystallization processes.
