Which outcome occurs when molten steel cools imperfectly?

💡 Explanation

Microsegregation concentrates impurities at grain boundaries during the *nonequilibrium solidification* of steel, because elements redistribute rather than maintaining a uniform mixture. Therefore, material strength decreases rather than the mixture solidifying rapidly.
