Description

The Grenoble drop tube first experiments and results on pure W and Re droplets are presented. High absolute amounts of undercooling have been reached (530 K for W and 975 K for Re). The solidified samples are single crystals in the case of W and polycrystals in the case of Re. The liquid-solid interfacial energy is derived from these experiments
