摘要: Abstract Influence of solidification rate on the interdendritic microstructure evolution a multiphase Ni3Al-based superalloy was investigated. Compared to original as cast sample, rapid leads high nucleation burst α-Cr precipitates in spray casting alloy, which promotes transformation from b.c.c. B2 β phase f.c.t. L10 martensite plates with density stacking faults and microtwins regions.
