History

Which risk increases during bronze casting's historical lost-wax process if vent holes are inadequately designed?

A)Increased tensile yield strength
B)Hot tears due to restrained contraction
C)Accelerated copper oxidation rates
D)Decreased alloy solidification temperature

💡 Explanation

Hot tears emerge because differential cooling causes internal stress, therefore exceeding bronze's tensile strength during solidification via constrained thermal contraction, rather than tensile strength because it's a brittle weakness not a strengthening.
