Which risk increased when Song Dynasty iron foundry output targets were aggressively increased?

💡 Explanation

Decreased tensile yield strength risks increased when hastily-produced iron results from incomplete processing. Quicker smelting often sacrifices thorough removal of impurities via slag tapping, which impedes lattice development because dislocations remain trapped, therefore weakening the alloy, rather than forming ductile wrought iron bars.
