用于微层裂现象诊断的Asay-F窗技术

Asay-F-Window Applied to Diagnostic of Micro-Spall Phenomena

针对现有测试技术在诊断强动载下金属样品表面"微层裂"现象存在明显不足的现状,设计发展了一种Asay-F窗技术,较准确地给出了金属样品表面"微层裂"物质的质量-速度分布信息,并通过与压电探针传统微喷测试技术诊断结果的对比,评估了其诊断能力及可靠性。

Quantitative data on micro-spall fragments production from metals mehed on shock or release are sparse because of diagnostic limitations. In this study, a new diagnostic technology Asay-F- Window was designed,and the mass-velocity distribution of micro-spall fragments was presented. By comparing the measured results of Asay-F-Window with those of piezoelectric pins, the reliability of Asav-F-Window technique was evaluated.
