Effect of Cooling Rates on Microstructure and Properties of VST5553 Alloy

Material behavior in high-speed range is a separate field of material science with its own laws and dependences different from and inapplicable to the low-speed range.

Military hardware traditionally establishes the requirements for materials subject to shock-and-wave stresses and used for armor application. Titanium alloys exhibit excellent specific strength and good potential to be used instead of traditional materials.

VSMPO developed VST2B alloy for armor application.

The alloy chemistry allows introduction of high amounts of scrap generated during manufacture of traditional alloys. This alloy possesses the excellent complex of properties.

This paper presents data on the properties corresponding to different types of structures obtained at low testing rate. It contains information on armor strength and results of ballistic tests with different types of striker bars and rate of exposure corresponding to different types of weapons.

This paper shows the structural dependence of results of ballistic tests.
