高速冲击下块体金属玻璃动力学响应的实验研究
Experimental study on dynamic response of bulk metallic glass under high velocity impact
摘要
Abstract
As a novel material with high strength,bulk metallic glass received concern of many researchers all over the world.For potential military applications,it was important to un-derstand the dynamic response of this material under high strain rate.To this end,Electric Gun was chosen to study dynamic response of a newly prepared Zr-based bulk metallic glass.In the E-lectric Gun experiments,the velocity of electric explosion driven plastic flyer in 0.5 mm thick-ness could reach 3 .5 km/s.Based on bulk metallic glass sample/window interface particle veloci-ty profiles measured by high resolution DPS laser interferometer,two important dynamic behav-iors were obtained under high strain rate about 106/s.In a shock pressure range of 15~25GPa, the Hugoniot elastic limit was determined to be about 2 .4GPa,and the shock wave velocity (Ds) vs.particle velocity (up)Hugoniot data were linearly fitted by Ds= (4.4±0.1)+(0.58±0.08)up.关键词
