Properties of Aluminium 1

[pdjolley]

Hi all,
I have to design an instrument for use at 60K. However, I do not know what happens (if anything) to the mechanical properties of materials at these temperatures. Does anyone have a link where I can find this out? I specifically need to know what happens to the yield strength of Al. 6061 at 60K.

thanks for any help
Paul

Hi pdjolly,
Yield strength of the T6 temper increases about 10,000 psi at 60K. Tensile strength also increases almost 20,000 psi.

If you want a graph, check in "Cryogenic Materials Data Handbook (Revised)" Fred R Schwartzber et al. July 1970.

Hi iainuts,
thanks for the information.

cheers

Mil handbook 5F has a plot of yield strength of 6061-t6 vs temperature. at -200 F it increases from room by 8%, by 14% at -300 and 30% at -400 F.
