Which material-related consequence emerged during early iterations in Ancient China integrating cast iron with rapid oxidation mechanisms involving manufactured gunpowder artillery?

💡 Explanation

Early cast iron cannon experienced frequent failures due to embrittlement because rapid heating and cooling cycles during black gunpowder explosions caused thermal shock weakening the metal that, even cast iron, cannot distribute or handle rapidly, rather than controlled burn rates due to inconsistent powder composition or proper controlled storage.
