This work is devoted to a detailed study of the structure of 3M titanium alloy, which is formed during the penetration of a target from this alloy by an irregularly shaped striker at a collision velocity of ~ 2 km/s. © 2020 The Authors.

Introduction Titanium alloys with a range of unique physical and mechanical properties are among the main structural materials and are used in a wide variety of industries. Among the unique properties include: high specific strength, corrosion resistance both in the atmosphere and in sea water and a number of aggressive environments, low moduli of elasticity, high heat resistance, non-magnetism, satisfactory manufacturability and some others. It is also believed that they are very promising for use in terms of protection against high-speed impact Minakov et al. (2007). Depending on the purpose and operating conditions of the products, titanium alloys must have a certain structure and a set of mechanical properties. To develop new types of alloys, it is necessary to conduct detailed studies of the This is an open ac der the CC BY-NC-ND license (https:/ 1st Virtual European Conference on Fracture Deformation and fracture of a titanium alloy during penetration of high-speed impactor to the target S.A.
