Dependency of microstructure and microhardness on withdrawal rate of Ti-43Al-2Cr-2Nb alloy prepared by electromagnetic cold crucible directional solidification

The intermetallic Ti-43Al-2Cr-2Nb (at.%) alloy was directionally solidified in an electromagnetic cold crucible with different withdrawal rates (V) ranging from 0.2 to 1.0 mm昺in-1, at a constant temperature gradients (G=18 K昺m-1) . Macrostructures of the alloy were observed by optical microscopy. Mi...
