Plots of average atomic volume of SS 21-6-9 versus pressure. The solid line represents our fitting result to Vinet EOS. The EOSs of pure hcp-iron determined by Mao et al .[ 21 ] and Dewaele et al .,[ 22 ] Fe-rich Ni alloy determined by Mao et al .[ 21 ] and Komabayashi et al .[ 27 ] are also illustrated together for comparison. The lower panel shows the difference between the present experimental and fitting results of hcp SS 21-6-9.
