Which impurity introduced during the bronze smelting process alters mechanical behavior?

💡 Explanation

The use of arsenic as an alloying element affects bronze properties, because it causes intergranular weakness via grain boundary segregation, leading to embrittlement. Therefore the bronze becomes brittle, rather than possessing increased ductility or corrosion resistance.

• In historical canal design, which construction problem increased substantially when survey data employed quadratic approximation rather than strictly linear interpolation?
• Which early catapult failure occurred because the counterweight design introduced excessive torsional stress?
• Which risk increases regarding load-bearing capacity when inconsistent brick quality affected foundation-raft construction during early ziggurat building?
• Which risk significantly increased in chinampa agriculture when using concentrated human waste?
• During the Bronze Age collapse (~1200 BCE), which contributing factor most directly exacerbated societal vulnerability after widespread drought?
• Which consequence resulted when Mesopotamian irrigation canal siltation decreased channel cross-sectional area?
