← HistoryWhich outcome occurred when bronze armor was work-hardened?
A)Reduced ductile to brittle transition
B)Increased resistance to brittle facture
C)Enhanced uniform plastic deformation✓
D)Lowered the metals oxidataion rate
💡 Explanation
Work hardening bronze increases dislocation density, improving yield strength because dislocation pile ups hinder continued slip. Therefore, pre-stressed bronze armor offers enhanced resistance to plastic deformation, rather than increased chance of facture under impact loading experienced during combat.
