← HistoryWhich 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.
