摘要: Shock-wave experiments on iron preheated to 1,573 K conducted from 14 73 GPa, yield new data for sound velocities of the {gamma}- and liquid-phases. Melting was observed in highest pressure ({approximately} 71 {+-} 2 GPa) at calculated shock temperatures 2,775 160 K. This single crossing {gamma}-liquid boundary measured here agrees closely with {gamma}-iron melting line determined by Boehler [1993], Saxena et al. Jephcoat Besedin [1997]. curve is {approximately} 300 C lower than that Shen [1998b] 80 GPa.
