Model Composite (Layered) Material on the Basis of Titanium

Abstract

Modern technology demands of material more and often incompatible requirements, for example, the combination of very high strength along the high fracture toughness and lightness. cently there appeared many publications on titanium alloys possess­ing much higher mechanical properties as compared with those known before. There are many publications about the improvement of properties of known alloys by using new kinds of heat treatment. By the latter is meant mild quenching including cooling in the furnace from the ß-field to the temperature of α+ß field followed by cooling in air (1);two stage aging, namely at first aging at the temperature of existing ω-phase and then at temperature field of (α+ß) phases (2); different variants of thermomechanical treatment (3,4). Additional doping of known grades of alloys is widely used with the purpose of increasing strength and toughness. New composites are being developed using multicomponent alloying and such elements as Cu, Si, As.(5,6)
