The alloy can be well directionally solidified as V = 8.33 μm/s and P = 45 kW or 48 kW.

The directional solidification alloy yields UTS 589.4 MPa and elongation 1.16%.

Nanoindentation hardness and lamellar width   has relation of H_N=16.12d−0.127$H_N=16.12d^{-0.127}$ and r²=0.992$r^2=0.992$.

Relation   is $H_N^{\text{'}}=16.09d^{\text{'}-0.127}$ and r'2=0.971$r^{\text{'}2}=0.971$as as-cast and HT considered.

B₂ phase is reduced by annealing and HT2 sample has a relatively better property.
