Credible Sources for Mechanical Properties of Metals

[flash3780]

I'm looking for a credible source for mechanical properties of a wide range of metals. In the past, I've worked with large companies who kept their own material data. But, I've recently moved to a smaller company with fewer resources, I was looking for a new source of credible data (vendor data usually isn't very good - and I'm sure that I'd get thrown out of a design review for mentioning Matweb). I know that MIL-HDBK-5 has good data, but I was hoping for a more extensive library.

I'm interested in mechanical properties of a wide range of alloys (such as SAE 4340, 7075-T6 Al, Inco 718, Udimet 700, Waspaloy, etc.) at various temperatures with high statistical confidence (-3sigma or 95/99). I'm looking for LCF at temp, yield strength vs temp, UTS vs temp, and stress/strain curves at temp, thermal conductivity vs temp, coefficient of thermal expansion vs temp, etc.

I was wondering if anyone has experience with the ASM Alloy Center that they could share; I don't want to shell out the registration money if they don't have the information I'm looking for - but it looks promising.

Also, (and I may be getting greedy) I was hoping for the data to be available in a format that could be input into various finite element codes. If the website is able to interpolate between test curves, that would be a bonus.

Thanks in advance for the help.

Give

a shot.

I'm not sure if it's perfect for you, but it's free.

Free is good.

Indeed, free is good. I often reference Matweb for preliminary designs and whatnot, but I was looking for something that would hold up in a design review. Vendors often report average properties for materials, when what you're often interested in are the minimum properties.

Nothing wrong with ASM. We had most of the ASM Handbook hardcopy volumes which both Product Engineering and Manufacturing Engineering referenced.

Can't beat ASTM material specifications. These hold up to any audit or review.

I agree with metengr, ASTM standards are the source to use for basic mechanical property requirements. They won't have any fatigue data, nor any statistical ranges. The ASM Alloy Center is an excellent resource, and will have a lot of what you are looking for.
