摘要
采用分离式霍普金森压杆(SHPB)实验技术,在不同的冲击载荷条件下,对钨锆合金(52.6/47.4)的动态压缩性能进行实验研究,获取该材料在发生反应与不反应情况下的应力-应变曲线,并分析该材料的冲击响应特性。结果表明:钨锆合金是一种典型的弹脆性含能结构材料,在冲击压缩过程中会出现中应变率(<500 s-1)脆性断裂(未反应)和高应变率(>1 000 s-1)冲击反应两种状态。
The dynamic compression mechanical properties of W- Zr alloy （52.6/47.4） under different dynamic loads were investigated using the Split Hopkinson Pressure Bar （SHPB）. The corresponding stress-strain curves of W-Zr alloy at different strain rates were obtained, and the dynamic behaviour was studied. The results show W-Zr alloy is a typical elastic-brittle material before reaction. The dynamic mechanical properties of W-Zr alloy are distinctly different, it will be broken to fragments at moderate strain rates（ 〈 500 s-1） and will react at high strain rates （ 〉 1 000 s-1） when subjected to impact loads.
