HLE steels; HSS
High yield strength steels, with yield strengths above 360 MPa.
High cycle fatigue (HCF)
Occurs when materials are subjected to stresses well below their elastic limit over a large number of cycles, typically after 10 5 cycles.
Oligocyclic fatigue; low cycle fatigue (LCF)
Occurs when materials are subjected to high stress variations, generally exceeding the elastic limit, over a small number of cycles up to approximately 10 4 cycles.
Throat (apotheme); throat length
Dimension of the weld bead at 45°.
Liquation; liquidation
Separation of a metal from its alloys...
