Research on Explosive Hardening of Titanium Grade 2

In this investigation, three different explosive materials have been used to improve the properties of titanium grade 2: ammonal, emulsion explosives, and plastic-bonded explosives. In order to establish the influence of explosive hardening on the properties of the treated alloys, tests were conducted, including microhardness testing, microstructure analysis, and tensile and corrosion tests. It has been found that it is possible to achieve a 40% increase in tensile strength using a plastic explosive (PBX) as an explosive material. On the other hand, the impact of the shock wave slightly decreased the corrosion resistance of titanium grade 2. The change in corrosion rate is less than 0.1 mu m/year, which does not significantly affect the overall corrosion resistance of the material. The reduction in corrosion resistance is probably due to the surface geometry changes as a result of explosive treatment.

Automated summary

In this investigation, the use of different explosive materials was explored as a means to enhance the properties of titanium grade 2. Tests, including microhardness testing, microstructure analysis, and tensile and corrosion tests, were conducted to examine the influence of explosive hardening on the treated alloys. It was found that plastic-bonded explosives (PBX) can achieve a 40% increase in tensile strength. However, the corrosion resistance of titanium grade 2 slightly decreased due to the impact of the shock wave, with a change in corrosion rate less than 0.1 mu m/year.
