Scientists from the National Research Technological University "MISiS" together with French
According to the authors, they combined the effect of both methods and thereby dramatically increased the useful characteristics of the resulting materials.
We applied GIP for materials that were not previouslywere recommended for such processing, since they have a loose surface due to the presence of open pores. In a special way, by applying a thin layer of the same metal to a loose product, we obtained a kind of hermetic capsule that allows us to successfully use GIP. Thanks to this treatment, porosity was reduced by more than half, compressive strength increased by 25 percent, and most importantly, tensile strength increased many times over.

In particular, the tensile strength of stainlesssteel and pure titanium increased approximately sevenfold. The most impressive results were obtained for the Ti6AL4V titanium-aluminum alloy, whose tensile strength increased 28 times. The improvement in mechanical properties is provided by diffusion of the material and changes in its microstructure, the scientists explained.
Now, based on the results of the work, a group of scientists plans to develop new materials for the medical industry.
