Abstract
Disclosed is a method of enhancing the shock absorbency of titanium-niobium system alloys consisting of 15-17.5 wt.% niobium and the rest titanium. The method is based on heat treatment which involves heating the alloy to 30-100 °C above the polymorphic transformation temperature of the alloy, followed by rapid cooling in a cold medium.

From table 1 it follows that the alloys of the titanium system are niobium, where the content of niobium is 15 to 17% by weight, has the largest damping property.
