Microstructure formation and columnar to equiaxed transition during cold crucible directional solidification of a high-Nb TiAl alloy

Microstructure formation and columnar to equiaxed transition during cold crucible directional solidification of a high-Nb TiAl alloy

In order to study the factors of columnar to equiaxed transition (CET) of high-Nb TiAl alloys, Ti46Al7Nb0.4W0.6Cr0.1B alloy has been fabricated by cold crucible directional solidification (CCDS) technique under different pulling rate from 3.3 μm/s to 16.7 μm/s. The marco/micro-structure and phase co...
