The optimization of the process of polymer film orientational drawing using the local heater was investigated. One of the problems with this technology is that the strength of the resulting fibers differs significantly from the theoretical estimates. It is assumed that one of the reasons is related to the peculiarity of this technology, when at the point of drawing the film is heated only on one side, which creates a temperature difference between the sides of the film in contact with the heater and the non-contact sides of the film in the air.

- - The study focused on VT1-0 titanium processed through rolling at various temperatures, resulting in an ultrafine-grained microstructure with nanometer-sized grains.
- - Annealing at 823 K for 1 hour caused grain coarsening and subgrain formation, impacting the material's creep behavior under constant load tests conducted between 648-723 K.
- - Analysis revealed that titanium processed at elevated and room temperatures exhibited better creep strength than that processed at cryogenic temperatures, with post-SPD annealing negatively affecting creep properties.
