When an alloy solidifies over a range of temperature, the resulting casting structure is Correct Answer Dendritic

Explanation:

  • The dendritic microstructure is the main microstructural constituent formed during the solidification process of single- or dual-phase Fe-based alloys.
  • During alloy solidification, a volume contraction accompanies the transition first from liquid to solid, and then in the solid as the temperature decreases.
  • The solidification of alloys results in a dendritic structure. The rapid dendrite growth is realized by the rapid movement of the liquid/solid interface toward the undercooled melt.


Note: The solidification of metal results in columnar structure.
