| Abstract | The Ni,Cr, Al-TaC composite was directionally cast from a nickel-base alloy with a nominal mass composition of Ni-10Cr 5.0Al-13.9Ta-0.9C (mass fraction. %). The morphologies of TaC in the in-situ composite was observed with AMRAY100B SEM. TEM investigations were preformed in a JEM-2000CX instrument at 150 kV. The experimental results show that TaC fibers are grown front the dendritic arms of the primary blocky TaC in the bottom of the d rectionally solidified Ni, Cr. Al-TaC sample. The longitudinal growth of TaC fibers is controlled by the pyramid growth mechanism under forced heat flow of [001] orientation. The transverse growth pattern of TaC is markedly affected by the unstable mode. The multiplicity of TaC transverse morphologies is presented. |
