Abstract

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 0.1µm/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.

摘要

在本研究中，使用了三种不同的爆炸材料来改善2级钛的性能：铵铝炸药、乳化炸药和塑料粘结炸药。为了确定爆炸硬化对处理后合金性能的影响，进行了多项测试，包括显微硬度测试、微观结构分析以及拉伸和腐蚀测试。研究发现，使用塑料炸药（PBX）作为爆炸材料，可使拉伸强度提高40%。另一方面，冲击波的影响使2级钛的耐腐蚀性略有下降。腐蚀速率的变化小于0.1µm/年，这对材料的整体耐腐蚀性没有显著影响。耐腐蚀性的降低可能是由于爆炸处理导致表面几何形状发生了变化。
