    摘要:

    基于梯度材料一維波系作用的簡化算法設(shè)計了Al-Cu梯度飛片材料的加載壓力曲線。通過熱壓法制備相應(yīng)的Al-Cu梯度材料，其表征后的阻抗性能與設(shè)計路徑相匹配。采用三維表面輪廓儀檢測Al-Cu梯度材料的平行度，并利用一級氣炮以400 m/s的速度發(fā)射Al-Cu梯度材料沖擊Al-LiF靶材。該實驗應(yīng)變率的結(jié)果證明了Al-Cu梯度材料能夠?qū)崿F(xiàn)高速沖擊實驗中應(yīng)變速率在104–105/s范圍的精確控制。

    Abstract:

    Based on simplified calculations of one-dimensional wave systems, loading pressure platform curves of Al-Cu gradient materials (GMs) impactor were designed. The Al-Cu GMs were prepared using tape-pressing sintering, and their acoustic properties were characterized to match the design path. The parallelism of the Al-Cu GM was confirmed using a three-dimensional surface profilometry machine. A one-stage light-gas gun was used to launch the Al-Cu GM, impacting an Al-LiF target at a velocity of 400 m/s. The results of the experimental strain rate demonstrate that the Al-Cu GMs can realize the precise control of the strain rate within the range of 104?105/s in the high-speed impact experiments.
