摘要
采用熔融玻璃自分离净化工艺,使得合金(Ni_(0.53)Fe_(0.33)Co_(0.14))_(73)B_(17)Si_8Nb_2获取深过冷观察到孪晶生长方式的凝固特征通过相成分及组织结构和形貌的分析,并结合深过冷液态合金凝固过程的特点。
Deep undercooling for Ni-base alloy, i.e., (Ni_(0.53)Fe_(0.33)Co_(0.14))_(73)B_(17)Si_8Nb_2, was
obtained by technique of auto-separating denucleation of molten glass. The solidification of
the undercooled Ni-base alloy is observed to be in a mode of twin growth. Mechanism on the
formation and growth of twins was approached by studies of composition, structure and
morphology of the alloy, together with the solidificatiion of deep undercooling alloy melt. The
undercooling, crystal lattice and composition of the alloy seem to be the most important fac-
tors in the formation and growth of twins.
