Which material characteristic improvement results when rapidly chilling crucible-cast crucible steel?

💡 Explanation

Rapid chilling causes reduced carbide precipitation along grain boundaries because it impedes carbon diffusion; therefore, it diminishes brittleness effects by dislocation hindrance rather than promoting boundary slip expected during slower cooling from annealing.
