Inhibition of stray grains at melt-back region for re-using seed to prepare Ni-based single crystal superalloys
Assisted by the mold preinstalled an alumina tube into seed segment, the influence of the original primary dendrite spacing of seed on the formation of stray grains at melt-back region was investigated during Ni-based single crystal casting using seeding method. The results showed that the interface...
