← HistoryWhich production outcome increased the vulnerability of early Damascus steel swords?
A)Carbon nanotube segregation✓
B)Homogenous ferrite grain growth
C)Austenite reversion kinetics
D)Cementite phase precipitation
💡 Explanation
The process allowed nanotubes to form, but non-uniform 'banding' of carbon nanotubes created areas of weakness; this is referred to as 'carbon nanotube segregation'. Therefore fracture toughness was reduced, rather than increased, creating more brittle blades.
