摘要：

A powder mixture of copper and graphite was dynamically shock-compressed by a rod-in-cylinder method. Structural characterization of the recovered specimen by transmission electron microscopy (TEM) showed the development of fine spherical diamond particles through shock-induced nuclei formation in the high pressure state and shock-assisted nuclei growth during unloading to ambient pressure via a solid-liquid-solid (SLS) phase transformation. A 2 μm large diamond particle was formed via a shock-induced martensitic path. Quantitative numerical simulation applying the two-dimensional computation code AUTODYN 2D was conducted to evaluate the pressure conditions during shock loading.© 1995 American Institute of Physics.
