2.4605 | Alloy 59 Fatigue fracture vs. overload fracture of a wire
Numeric designation | 2.4605 |
---|---|
Chemical designation | Alloy 59 |
The macroscopically completely deformation-free fatigue fracture (crack starting point at a groove in the surface) shows fatigue striations with a strongly crystallographically characterized orientation. The overload fracture forced by static tensile load, on the other hand, is ductile and characterized by the typical dimple patterns.
Material: Alloy 59 (2.4605; N06059) with 23% Cr and 15% Mo.
