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.
Infrared-induced ultrafast melting of nanostructured platinum films probed by an X-ray free-electron laser
理解金属的熔化是当前研究的一个热点。这可以通过用红外(IR)激光辐射泵浦系统,并用由X射线自由电子激光(XFEL)产生的硬X射线探测它来实现。在这项工作中,我们研究了纳米结构的多晶薄膜的铂照射的红外辐射的增加通量。我们的特点是结构响应以及成核和传播的液相作为一个函数的时间延迟之间的IR泵和X射线探针。我们观察到部分熔融的样品的IR能量密度高于200 mJ $\cdot$ cm $^{-2}$。为了拟合液相对铂中散射图案的贡献,我们应用了液态金属的模型。进行双温度模型模拟,以了解作为时间延迟和通量的函数的样品加热过程的固态分数。
