SN Curve Information for "Pure Nickel"? any ideas?

SN Curve Information for "Pure Nickel"? any ideas?

(OP)
Hello, we are undertaking a fatigue analysis on a nickel insert created by a vapor deposition process. I cannot find any information on SN curves for nickel as a meterial, the only information i can find relates to nickel alloys. Does any one know where i can get such information?

Cheers

RE: SN Curve Information for "Pure Nickel"? any ideas?

I doubt that any information exists for your specific application.  Maybe Special Metals has some information on essentially unalloyed wrought nickel, but that may not be suitable for extrapolating to a micrometer-scale coating applied by PVD.  Also, the load case you probably need (huge compressive/through thickness stress, low in-plane tensile stress) won't be the same as a typical rotating bending or fully reversed tension/compression load case.  Physical part testing may be your only recourse.

are you testing an isolated nickle part or a nickle layer on a substrate? there are no cook book curves to draw on, a lot depends on the substrate material and the degree of bonding, heat treating, and so on

Hello, we are looking for information on the pure NVD process, so this is without a substrate material. Thank you.

You could contact the Nickel institute. They might be able to direct you to the info you are looking for...
