Within early Chinese iron foundries, which outcome resulted from repeatedly exceeding the pig iron's temperature maintenance limit?

💡 Explanation

Exceeding temperature limits introduced rapid cooling and carbide formation via cementite decomposition, therefore eutectic carbide precipitation occurs, rather than graphite formation because silicon content influenced phases. Slow cooling encourages graphitization instead.
