用Mo、Ta和W在高压下的热膨胀研究压缩Ar的液-液相变

Evidence of liquid-liquid phase transition in compressed Ar probed by the thermal expansion of Mo, Ta and W at high pressures

Joseph Gal

摘要:

用金刚石对顶砧(DAC)测量的体心立方结构的Mo、Ta、W和V金属的熔化曲线与冲击动力学实验之间长期存在的争论,用这些过渡金属的热膨胀压缩液态或固态传压介质的行为来解释。这解释了文献中报道的含有不同传输介质的激光加热DAC实验中观察到的等压行为,从而解决了许多出版物中描述的长期谜团。

英文摘要:

The long standing controversy between the melting curves of the bcc Mo,Ta,W and vanadium (V) metals measured by diamond anvil Cells (DAC) and the shock dynamic experiments is explained by the behavior the liquid or solid pressure transmitting mediums compressed by the thermal expansion of the these transition metals. This explains the observed isobaric behavior of the laser heated DAC experiments containing different transmitting mediums reported in the literature, thus solving the standing enigma described in very many publications.
