In the article it was suggested to simulate the process of super-plastic deformation on optically transparent materials, created on diene and vinyl-aromatic carbohydrates, polar softener and achromatic stabilizer. It was shown that the index of rate hardening of such materials could change from 0.2 to 1.0 within the rate intervals of super-plastic deformation. The authors are convinced that prior to this article the alloy Sn-38%Pb was the best material for simulation of the processes of super-plastic deformation. Advantages and disadvantages of tin-lead alloy for simulation of super-plastic deformation were mentioned in the article. The article contains examples of chemical composition of new materials: the foundation (component content – 100 weight parts) – butadienesterene, isoprenesterene, butadiene-α- metylsterene; stabilizer (component content – 0.5 weight parts) – 2,6-ditretbutyl-4-metylphenol; polar softener (component content – 5-40 weight parts) – dibutylphtalate, dibutylsebacate. It was shown that introduction of polar softener reduces the effort of material flow. An unsufficient alternation of softeners content allowed modifying either behaviour of an alloy with different super-plastic structure or various temperature conditions of deforming.
