Fatigue strength: PH1 steel (Vxx/TMS)
This page presents the S-N curves and fatigue limit of PH1 steel samples that underwent heat treatment, machining that removed allowance of 0.5mm and shot-peening (in that order), obtained using the bending tests of rotating bars with AM layers normal to the axis of rotation.
Production and prost-processing conditions
Build orientation of longitudinal axis | vertical |
---|---|
Position with respect to inert gas flow | undefined |
Post-processing | heat treatment → machining allowance 0.5mm → shot-peening |
Experimental S-N curve
Wöhler curve
Fatigue limit (MPa) | 433 |
---|---|
Number of cycles to failure N | N=4,29⋅10<html>33</html>⋅S<html>-10,10</html> |
Stress amplitude S (MPa) | S=2136⋅N<html>-0,099</html> |
Explanation of the terms are given at the page Fatigue strength description.
This page is a part of the section DMLS/SLM: Fatigue design rules.
